... for each state of consciousness, and each neuron is a tiny oscillator passing waves of information through an intricately coupled network. So applying the dynamics of resonant oscillators and harmonic wave interference to human perception and...
... a synchronous discharge of cortical and thalamic neurons. Although many functions have been attributed to such synchronous firing, it is not known whether or how synchrony of firing per se affects thalamocortical operations. Direct experimental test...
Serotonin and brain: evolution, neuroplasticity, and homeostasis
... released by the presynaptic endings of neurons that have specialized actions through specific receptors on the membrane potential of postsynaptic neurons. However, these chemicals have more complex functions both within the neuron and on...
Hypnotic Entrainment and Induced Trance States
... of consciousness are created by the act of neurons firing in a network. When a single neuron fires once it is not a big event, but when a neuron fires in a rapid sequence then it is signaling other neurons with a fine vibration of wave spikes;...
Uncoiling the spiral: Maths and hallucinations
... low neural activity in V1 — regions where the neurons are firing very rapidly and regions where they are not firing rapidly. To translate visual patterns to neural activity, what is needed is a coordinate map, a rule which links each point in the...
... and more responsive connections. The more a neuron or assembly of neurons is used in a specific exercise, the faster and more responsive those neurons will become when performing that exercise. This is how the brain learns new things and integr...
PET and MRI of the thalamus in never-medicated patients with schizophrenia
... with reported greater decreases in total neuron number than of neuron density in the thalami of schizophrenic patients. The area of the thalamus was smaller in the patients than in the volunteers, and this difference was greatest in the left...
neurons communicate with one another via synapses, where the axon terminal or en passant boutons (terminals located along the length of the axon) of one cell impinges upon another neuron's dendrite, soma or, less commonly, axon. Neurons such as Purki...
... have one the signal which is to calm down the neuron. And if you therefore put a chemical which increases that, that will calm you down or send you to sleep, if that's what sleeping pills are. And we've seen that, of course, recently in things li...
Cortical Region Interactions and the Functional Role of Apical Dendrites
... in various connectionist models that employ neurons with functionally distinct apical and basal compartments. A neuron in which separate sets ofinputs can be integrated independently has the potential to operate in a variety ofways not possible...
Presynaptic regulation of recurrent excitation by D1 receptors in prefrontal circuits
... disorders, including schizophrenia. Prefrontal neurons are distinguished by their capacity for sustained activity during the time a stimulus is held in memory, and this mnemonic response is considered a substrate for a variety of cognitive functio...
Timewarp: How your brain creates the fourth dimension
... our attention and evokes the firing of many neurons across the brain, he says, causing us to soak up more sensory details (Philosophical Transactions of the Royal Society B, vol 364, p 1841). Richer memories seem to last longer, he says, becaus...
