Bioprograms
The networks of neurons built by our inherited DNA that are developed by the time we are born. These networks provide the basic framework for our ability to function as a living organism and to learn. They co-ordinate and control the functions of our bodies. They give us the general ability to register and eventually learn to respond to sensory stimuli. The input networks are able to grow new dendrites and axons which, in response to the repetition of specific sounds, sights, feelings, tastes and smells, build networks specifically to recognise these statistical regularities. On the output side the bioprograms are capable of operating all our muscles and stimulating all our glands.

Bit
The smallest measurable unit of machine (artificial) information.

Electro Encephalo Graph (EEG).
Records electrical activity in the brain to identify the position and strength of various areas of the brain to help identify their functions

Emergent
The properties of an organism that are not possessed by its parts, but are observed to ‘emerge’ as a result of the functioning of the whole. The opposite of ‘Reductionism’.

Energy
The capacity or power to produce an effect. It is the property of a system that is a measure of its capacity for doing work. Energy comes in a variety of forms: electrical, thermal, chemical, nuclear, radiant, and mechanical.

Epistemology
Theory of Knowledge

 

Eukaryotic cells
Eukaryotic cells (from the Greek meaning truly nuclear) comprise all of the life kingdoms except monera. They can be easily distinguished through a membrane-bound nucleus. Eukaryotic cells also contain many internal membrane-bound structures called organelles. These organelles such as the mitochondrion or chloroplast serve to perform metabolic functions and energy conversion. Other organelles like intracellular filaments provide structural support and cellular motility.

Evolution
Literally, a process of unrolling or opening out. In the 1830s this word was first applied to the historical transmutation of organisms; by the 1860s and 1870s it had come to refer to a general process of biological transmutation, which was commonly assumed to be directional or progressive. Darwin’s theory of evolution by natural selection suggested that this process was blind and purpose­less, which became the central concept in neo-Darwinism, the dominant orthodoxy of modern biology. Other evolutionary philosophies suggest an inherently creative principle in the evolutionary process, which manifests a directional or purposive principle. For some modern cosmologists, the entire universe is an evolu­tionary system.

Field
A region of physical influence. Fields connect matter and energy within their realm of influence. Fields are not a form of matter; rather, matter is energy bound within fields. In current physics, several kinds of fundamental field are recognized: the gravitational and electro-magnetic fields and the matter fields of quantum physics.

Force
The active power, strength or energy brought to bear, which alters the state of rest or motion of a body.

Form
The shape, configuration, or structure of something, as distinguished from its material. In the Platonic tradition, the term Form is used to trans­late the Greek term eidos and is interchangeable with the term Idea. Partic­ular things we experience in the world participate in their eternal Forms, which transcend space and time. By contrast, in the Aristotelian tradition, the forms of things are immanent in the things themselves. Forms have no objective reality independent of our own minds.

Gene / genome
See DNA.

Genotype
The genetic constitution of an organism. See Phenotype

Glial cell
Any of the non-neuronal constituent cells of the brain or the peripheral nervous system. The majority of the brain’s cells are glia, not neurons.

Glia Bridges
Strings of glia cells that develop between two active neurons, providing a temporary channel capable of passing a neural impulse from one neuron to stimulate the other. If a temporary link is not used again, it dissolves. If a temporary link continues to be activated, the ‘bridge’ is strengthened. Further activity stimulates the neural nucleus to replace this temporary link with a permanent dendrite or axon filament. In this way the components of new neural networks are automatically created in response to the initial neural stimulation.

Heredity
The transmission of characters from ancestors to their descendents. Originally understood in a broad sense which included the inheritance of acquired characteristics and habits of life; restricted in modern biology to mean the inheritance of genes

Hippocampus
A part of the brain under the cerebral cortex traditionally associated with memory.

Holism
The doctrine that wholes are more than the sum of their parts

Hormone
A peptide produced by one tissue and conveyed by the bloodstream to another to effect a change in physiolog­ical activity, such as growth or metabolism. Many hormones are known to affect mood, and therefore the efficiency of the brain’s response to stimuli.

Hypothalamus
A region of the brain thought to secrete hormones involved in hunger, thirst, sex etc.

 

Imagination see Appendix

 

Information
To inform literally means to put into form or shape. Informa­tion is now generally taken to be the source of form or order in the world. For example in the concept of “genetic information” it is the sequencing of nucleotide bases that dictates the form of a new living organism.

 

“Information is information; it is neither matter nor energy.” (Norbert Weiner 1961). See potential (matter) and kinetic (energy) information 

Information theory
A branch of cybernetics that attempts to define the amount of information required to control a process of given complexity. Information in this narrow technical sense is measured in bits. A bit is the amount of information required to specify one of two alternatives, for example to distinguish between 1 and 0 in the binary notation used in computers.

See Appendix

 

Intelligence see Appendix

Kinetic Information
Information that is active and can do work. See ‘Potential Information’. 

Knowledge
Based on language, classification, definition, association, cross references, notation, measurement, Observation, Statistical regularities, Pattern invariance.

 

Lamarckian inheritance
The inheritance of acquired characteristics. Until the late nineteenth century, it was generally believed that an organism’s descendents could benefit from the accumulated experience of their ancestors, and both Lamarck and Darwin shared this general opinion. It went out of fashion in the twentieth century, largely because no one could conceive how such a process might operate, and the concept that genes mutate randomly became orthodox.

Ligand
From the Latin ligare, “that which binds” (same root as religion). A variety of small molecules that bind to cellular receptors and convey information to the cell.

Limbic system
The system of the brain primarily associated with memory and emotion.

Kinesin.   A protein that converts ATP (Adenosine Triphosphate) into motion.

Magnetic Resonance Imaging (MRI)
A method of scanning the brain based on the resonance of atomic nuclei. This process enables the neurons of a live and fully operational brain to be monitored by showing the uptake of sucrose, which is thought to be a good guide to their level of activity. MRI scanning enables experiments to be carried out to try and determine brain activity associated with various activities.

fMRI Scans 3d image in real time.

Matter
In Newtonian physics, matter, distinguished by mass and extension, was contrasted with energy. According to relativity theory, mass and energy are mutually trans­formable, and material systems are now regarded as forms of energy.

Memory
The capacity for remembering, recalling, recollecting, or recogniz­ing. In the hypothesis outlined in this book memory is a set of instructions. A group of neural networks that initiates an activity.

Mind
Term referring to that part of our consciousness that thinks and makes decisions. In Cartesian dualism, the conscious thinking mind is distinct from the material body; e.g. the mind is non-material. Materialists postulate that the mind derives from the physical activity of the brain. Psychologists point out that the conscious mind is associated with a much broader or deeper mental system, the unconscious mind. In the view of Jung, this unconscious mind is not merely individual but collective.

Mitochondria
In cell biology, a mitochondrion (plural mitochondria) is a membrane-enclosed organelle found in most eukaryotic cells. These organelles range from 0.5 to 1.0 micrometer in diameter. Mitochondria are sometimes described as “cellular power plants” because they generate most of the cell’s supply of adenosine triphosphate (ATP), used as a source of chemical energy. In addition to supplying cellular energy, mitochondria are involved in other tasks such as signaling, cellular differentiation, cell death, as well as the control of the cell cycle and cell growth.

MOOCS
Massive open online course. Distance Learning

Mutation
A sudden change. Mutations can generally be traced to changes in the genetic material. The term mutation is now generally taken to mean a random change in a gene. 

Molecule
A chemical unit made up of three or many more atoms. Each kind of molecule has a characteristic atomic composition, a specific structure, and specific physical and chemical properties. See Atom.

Monera Cells
Monera are bacteria and other mostly tiny, single-celled organisms whose genetic material is loose in the cell. The genetic material of plants, animals usually referred to as Archaea.

MRI Scans
Magnetic Resonance Imaging Scanners Uses the blood-oxygen-level-dependent (BOLD) contrast, discovered by Seiji Ogawa

fMRI
Functional MRI scans

rtfMRI
Real Time functional MRI

Neo-Darwinism
The modern version of the Darwinian theory of evolution by natural selection. It differs from Darwin’s theory in that it denies the possibility of Lamarckian inheritance; heredity is explained solely in terms of inherited genes.

Neural Correlate
The neural activity that causes some sensation or activity

Neural Modules: Neurules
Neural modules Also Chunking; Mental subroutines, Neural enclosures, Memes, Engrams, Cell Assemblies (HEBB), Mental subroutines, Basic unit of memory, ideas and concepts.

Neuron

The principal component of the nervous system. Each Neuron consists of a cell nucleus and branched protoplasmic extensions that receive impulses from adjacent cells (dendrites); and transmit impulses away from the nucleus (axons). Also called nerve cells. Neurons are usually associated with the brain and the control of muscles, but their presence in close association with all the glands and tissue immune cells suggests they are also involved in many other interactions especially between the immune system and the nervous system.

Neurogenesis
The process whereby new neurons are grown that are not caused, influenced or directed by the inherited DNA.

Neuropeptide
One of nearly 100 small peptide substances.

Neurotransmitter
A chemical substance, such as acetylcholine or dopa­mine, that transmits nerve impulses across a synapse.

Ontology

Oxyrhynchus
Collection of pre-Christian papyri found near Cairo.

Paradigm
An example or pattern. In the sense of T. S. Kuhn (1970), scientific paradigms are general ways of seeing the world that are shared by members of a community, and they provide models of acceptable ways in which problems can be solved.

Peptide see PNA
Any of various natural or synthetic compounds containing two or more amino acids linked by the carboxyl group of one amino acid and the amino group of another. By definition, polypeptides are the larger peptides, usually those with in excess of 100 amino acids. They are smaller than the proteins, which may have 200 or more amino acids as well as other attached molecules, such as sugars or lipids.

Peripheral nervous system
The peripheral nervous system is the system of nerves that links the brain and the central nervous system to the rest of the human body. Sensory nerve dendrite filaments carry impulses from sense receptors to the central nervous system. Motor nerve axon filaments carry impulses from the central nervous system to the muscles and glands.

Phenotype

Positron Emission Tomography (PET Scan)
A means of studying the living brain based on the transmission of positrons

Protein
A complex organic macromolecule composed of many amino acids linked together in chains, called polypeptide chains. There are many different kinds of protein molecule. Proteins are fundamental components of all living cells and include many substances, such as enzymes, hormones, and anti bodies, that are necessary for the proper functioning of an organism.

The sequence of amino acids is specified by the sequence of nucleotides in the DNA of genes. There may be one or more such chains in a protein, and the chains are folded up into characteristic three-dimensional configurations, which are thought to determine the function that the cell carries out.

Pythagoreanism.
The belief that the universe is somehow essentially mathe­matical and that everything can be understood in terms of patterns. This philosophy had a strong influence on Plato. Memory could be said to be patterns of neural activity.

Quadrivium
Medieval curriculum http://en.wikipedia.org/wiki/quadrivium

The quadrivium was considered preparatory work for the serious study of

philosophy (sometimes called the “liberal art par excellence”) and theology.

Superconducting Quantum Interference Device (Squid)
An instrument for detecting changes in the very small magnetic fields in the brain

Synapse
The very narrow gap that forms all the junctions between individual neurons, and between neurons and the other sensory or motor cells like those in the eyes, ears, tongue, skin, nose and the muscles or glands.

Synaptic Tension
The strength of the energy holding the two constituents of the synapse together. If the tension is high and so the width of the synaptic gap is at its minimum then the communication across the junction will be fast and efficient, a state associated with being awake, alert, aware and conscious. If the synaptic tension falls and the gap widens, then communication across the junction will diminish and slow down, a state associated with being drowsy, asleep, unconscious or anaesthetised. The swift raising of the level of synaptic tension across a particular section of the brain may account for the way we can focus quickly on a new activity and so respond to a new situation immediately.

Systems theory
A form of holism concerned with the organization and properties of “systems” at all levels of complexity. Much of the early inspira­tion for this approach came from an attempt to establish parallels between physiological systems in biology and social systems in the social sciences. The systems approach has been deeply influenced by the study of cybernetics. The central theme of much systems thinking is the self-organising and self-regulating machine or organism.

Teleodynamic End directed activities

Teleology
The study of ends or final causes; the explanation of phenomena by reference to goals or purposes.

Teleonomy
