instrumental conditioning
You are listening to a song on the radio while doing your homework. the phone rings. your mother has called to tell you that your favorite uncle has died after being hit by a car. three months later you again hear the same song and suddenly feel very sad. in this example, the unconditional response is
you feeling sad when your mother calls with the bad news

In classical conditioning, a neutral stimulus
is paired repeatedly with a stimulus that evokes a reflexive response
Instrumental conditioning involves strengthening connections between
circuits that detect a stimulus and motor control circuit that produce a response.
One striking aspect of H.M.'s memory deficit is that he

myelination of brain nerve axon membrane is accomplished by_____

Explain how a message is transmitted within a neuron
describe EPSP, IPSP(movement of ions involved), summation, threshold of excitation (axon hillock)
Describe membrane potential
The membrane potential is caused by an unequal distribution of ions (charged particles) inside and outside the axon. Four ions determine the membrane potential: sodium (Na+), chloride (Cl-), Potassium (k+), and Anions (A-). the membrane potential is a compromise between two factors: diffusion and electrostatic pressure. The force of diffusion is caused by thermal agitation. Particles found in high concentrations in one part tend to spread toward the region of low concentration. The force of diffusion acts on each ion by: CI- tends to enter the axon because it is more concentraed outside. Similiaryly Na+ tends to enter, and K+tends to leave. The organic anions, A- would leave the axon but cannot because they are so large. Electrostatic pressure is the repulsion between particles with like charges and the attraction unlike particles: the negative charge tends to push CI- out but attracts Na+ and the positive charge outside the axon tends to push K+ in.
Explain the necessary steps for depolarization of an NMDA recptor. Explain what molecules must bing to the receptor.
The NMDA receptor controls calcium ion channels. This channel is normally blocked by magnesium ion, which prevents calcium ions from entering the cell even when the receptor is stimulated by glutamate. If membrane is depolarized magnesium is dejected and the channel is free to admit calcium ions. neurotransmitter and voltage dependent.
