Learning and Memory: Habituation, Sensitization, and Brain Mechanisms

These flashcards cover key vocabulary related to the concepts of learning, memory, habituation, sensitization, and various brain mechanisms discussed in the lecture.

Habituation

Sensitization

An increase in response to a stimulus after exposure to a strong or noxious stimulus.

Gill Withdrawal Reflex

A reflex in Aplysia involving retraction of the gill when the siphon is touched.

Long Term Potentiation (LTP)

A long-lasting strengthening of synapses based on recent patterns of activity.

NMDA receptors

Glutamate receptors that play a key role in synaptic plasticity and memory function.

Anterograde Amnesia

The inability to form new memories following an event.

Retrograde Amnesia

The loss of pre-existing memories prior to an event.

Papez's Circuit

A neural circuit involved in the control of emotional expression and memory.

Korsakoff's Syndrome

A condition caused by thiamine deficiency, leading to memory issues and confabulation.

Prefrontal Cortex

The area of the brain responsible for higher cognitive functions and short-term memory.

Cerebellum

A brain structure involved in motor control and, potentially, procedural memory.

Amygdala

A brain region linked to emotion processing and memory, particularly stress-related memories.
