Document Summary
Describe 5 steps implicated in neurotransmitter release and what this process is called (6 points: actin potential reaches the synaptic termina, voltage gated ca2+ channels open. Produced in the ventricular zone around central canal of neural tube. Migrate by glial-mediated and somal translocation embryonic development of the central nervous sytem multiple functions of neurotrophins: -sensory areas: first few months motor areas soon after sensory. --many initially formed synapses are lost, remaining synapses are refined. -use it or lose it dendritic branching: parallels pattern of migration. -deeper layer migrate first and are first to sprout dendrites postnatal development of prefrontal cortex relatively slow, more gradual development into late adolescence linked to parallel development of higher cognitive functions . Draw one card at a time and sort them (according to whatever rule seems appropriate) Told by experimentor whether well sorted or not patient guesses the sorting rule (e. g. colour) Experimenter changes the rule without warning that"s not correct .
