Describe how the NMDA type of glutamate receptor is the physiological mechanism of forming associative memories.

Explanation: glutamate and glycine (or D-serine) bind to it, and when activated it allows positively charged ions to flow through the cell membrane. The NMDA receptor is very important for controlling synaptic plasticity and memory function. The NMDAR is a specific type of ionotropic glutamate receptor.

Describe how the NMDA type of glutamate receptor is the physiological mechanism of forming associative memories.

NMDA receptor channel plays an important role in synaptic plasticity and synapse formation underlying memory, learning and formation of neural network during development in the central nervous system. Overreactivating of the receptor causes excessive influx of Ca++ can lead to excitotoxicity which is implied to be involved in some neurodegenerative disorders.

answer: the answer is d.

explanation: this is because when you exercise you make your muscle produce a certain liquid, that does not evaporate it.   also when you exercise you do not reduce muscle fiber.   and it does not really control your twitch that much.
