John Douglas Jack Pettigrew born 1943 is Emeritus Professor of Physiology and Director of the Vision, Touch and Hearing Research Centre at the University of Queensland in Australia . Professor Pettigrew s research interest is in comparative neuroscience . He has studied a variety of different birds and mammals with modern neural tracing techniques to unravel principles of brain organization. He was the chief proponent of the Flying primates theory , which was based on the similarity between the brains of megabats and primates . Special emphasis is placed on the visual, auditory and somatosensory systems. ref name jack http profiles.bacs.uq.edu.au Jack.Pettigrew.html Emeritus Prof Jack Pettigrew ref Professor Pettigrew was the first person to clarify the neurobiological basis of stereopsis when he described neurones sensitive to binocular disparity . His recent studies indicate a role for non visual pathways in the phenomenon of developmental plasticity during the postnatal critical period . He discovered that owls have independently evolved a system of binocular neurones like those found in mammals. Recent work uses binocular rivalry as an assay for interhemispheric switching, whose rhythm is altered in bipolar disorder . ref name jack His scientific work was recognized by several honours and awards, including becoming a Fellow of the Royal Society of London Fellow of the Royal Society FRS and Fellow of the Australian Academy of Science FAAS .

Context date October 2009 Slow After Hyperpolarisation sAHP refers to a prolonged period of hyperpolarisation in a neuron or cardiomyocyte following an action potential or other depolarising spike. In neural circuitry, a train of action potentials may be required to induce a sAHP this is unlike fast AHPs which require no more than a single action potential. sAHPs are due to an extended potassium flux via calcium activated potassium channels I sub KCa sub ref P. Sah, Ca 2 activated K currents in neurones types, physiological roles and modulation. Trends Neurosci. 19 1996 150 154 ref ref P.

The resulting hyperpolarisation lasts for several seconds in a sAHP and effectively inhibits neural activity for this period. Fast and Medium AHPs have shorter periods.

The book The Mechanism of Mind details the underpinning model of mind that leads to the many thinking skills developed by Edward de Bono , including lateral thinking . The Model The model detailed in the book, and referred to again in many of Edward de Bono s other books, is one of Neurones networked together by many stronger and weaker connections and activating as a result of input stimulus or stimulation from other neurones that are themselves active. Neurones that are active together form stronger connections and are more likely to activate together in the future. The model is a Self organizing system . It is not intended that the model be a detailed analysis of how human brains are structured but the broadest possible abstraction that can provide meaningful understanding of the nature of thinking. Nor is it intended to build a cohesive theory but to provide the reader with a collection of concepts that will illuminate further thinking about thinking. More detailed models and theories specifically about the brain can be found under the topic of Cognitive Science and connectionism . Behaviour of the Model The characteristic behaviour of the system is shown to create and reinforce patterns. The current set of patterns in the system determine how new experiences are integrated. Attention tends to flow along well worn paths and patterns have large catchment areas. Novel experiences are often lost as attention flows down old paths that are in some way similar to the new experience. Sometimes starting at a different point in an established pattern can lead to a jump out of that pattern to a new one. These behaviours are analogs to human thinking behaviours such as circular thinking, prejudice, polarisation, insight and humour. Consequences The mind as modeled has some severe limitations.

This in turn causes them to go into a permanent contraction which makes flying and respiration physiology respiration impossible, and the insects then die of asphyxiation . Fly spray contains chemicals including many organophosphate compounds that bind to and permanently block the action of an enzyme called acetylcholinesterase. Acetyl choline ACh is the nerve transmitter substance released by motor neurones at a site called the neuromuscular junction to stimulate muscle contraction. The muscles relax stops contracting when the ACh is removed from the neuromuscular junction NMJ by the action of acetylcholinesterase. By inhibiting the cholinesterase the fly can no longer break down ACh in the NMJ and so its muscles lock up in a state of tetany continuous contraction making flying and respiration impossible. Fly spray is dangerous to pets as well as fish and should be used with caution. References reflist DEFAULTSORT Fly Spray Category Insecticides insect stub ... more details

Low threshold spikes LTS refer to action potential s generated from a membrane potential negative to that for sodium spike threshold firing level . gallery Deleted image removed File Low threshold spikes.png Low threshold spikes gallery Events It occurs when the neuron is maintained 150ms in a hyperpolarised state 70mV state which deinactivates T type calcium channel . Upon receiving excitatory stimulation glutamate , this causes a small depolarisation, allowing the T type Ca channel to open for a period 100ms and this influx of Ca depolarises the neuron. This results in a Ca spike with a characteristic triangular shaped depolarisation which is important for the influx of Na ions to further depolarise the neuron resulting in a number between 2 8 of action potentials, with interval between each AP less than 5ms. The T type Ca channels close after 100ms from opening and must remain closed for at least another 100ms before another set of LTS can occur. The functional significance of having multiple APs is so that these can add together in the next neuron to allow temporal summation and a higher probability that it will activate the next neuron in the circuit Origin These LTSs were originally observed in inferior olive neurons ref Llinas and Yarom 1981 ref and then in thalamic neurons. ref Llinas and Jahnsen 1982 ref Notes references References Llinas, R. and Yarom, Y. 1981 Properties and distribution of ionic conductances generating electroresponsiveness of mammalian inferior olivary neurones in vitro .

Endocannabinoid reuptake inhibitors eCBRI , similar to cannabinoid reuptake inhibitors CBRI , are substances which limit or completely stop the reabsorption of endocannabinoid neurotransmitters into their corresponding pre synaptic neuron es. Etymology There are several parts to the phrase endocannabinoid reuptake inhibitor. First, a reuptake inhibitor is a substance that prevents its respective neurotransmitters from being reabsorbed into the pre sypnatic neurones, which makes them continually recycle themselves, thus creating a large increase in neurotransmission. Next, a cannabinoid is simply a class of closely related substances such as Tetrahydrocannabinol and Cannabidiol . Endo is a prefix used to describe a cannabinoid that is naturally found within an animal. In retrospect, an endocannabinoid reuptake inhibitor is a substance that when ingested by an animal prevents reuptake of its endogenous cannabinoids. Pharmacology The inhibition of endocannabinoid reuptake raises the amount of those neurotransmitters available in the synaptic cleft and therefore increases neurotransmission . Following the increase of neurotransmission in the endocannabinoid system is the stimulation of its functions which, in humans, include suppression of pain perception analgesia , increased appetite , Mood psychology mood elevation and inhibition of short term memory . Use in medicine Other than toxicity research and recreational use, eCBRIs could have some potential in fighting tumors and possibly cancer . A study done in 2004 on rats with thyroid tumors showed that reuptake inhibition of the endocannabinoid system using VDM 11 and AA 5 HT reduced the ultimate size of the tumors in the treated rats. These findings suggest that the use of cannabinoids and or eCBR inhibitors could be used to effectively treat tumors and or cancer, which only adds to the controversy around cannabinoids and the cannabis plant as medicine. As one might expect, combining a cannabinoid receptor antagonist ... more details
