The CNS Efficiency Model of the Chiropractic Subluxation

This involves not only stabilizing the formation of the individual circuits, but also providing for general mean ...

U3 Neurobiology Summary
... Elaboration is where facts are easier to transfer into the LTM if they are part of a bigger ‘story’, e.g. phosphofructokinase is easier to remember as part of the whole respiratory pathway than a single fact. Encoding is the conversion of one or more nerve impulses into a form that can be received a ...

A Primer on Neurobiology and the Brain for Information Systems
... The functioning of the nervous system can be described in five stages (shown in Fig. 2.3). First, receptors detect changes in the internal and external environments. Such receptors are somatic-sensory (e.g., located in the skin to provide information on touch, pressure, pain, and temperature sensatio ...
