Study Notes
Neurotransmitters
- Glutamate is the primary excitatory neurotransmitter.
Glutamate's Effects
- Excessive amount of glutamate in the brain can lead to excitotoxicity, causing damage to neurons.
Glutamate Receptors
- NMDA (N-Methyl-D-Aspartate) and AMPA (Alpha-Amino-3-Hydroxy-5-Methyl-4-Isoxazole Propionic Acid) receptors are responsible for controlling the sodium channel in response to glutamate.
Strengthening Synaptic Connections
- Long-Term Potentiation (LTP) is the mechanism responsible for the strengthening of synaptic connections.
Glutamate Release
- High amount of glutamate released into the synaptic cleft can activate NMDA receptors, leading to an influx of calcium ions, which in turn strengthens synaptic connections.
NMDA Receptors' Role
- NMDA receptors play a crucial role in increasing synaptic connection strength by allowing an influx of calcium ions, leading to LTP.
Long-Term Depression
- The purpose of Long-Term Depression (LTD) is to weaken synaptic connections, counterbalancing the strengthening effects of LTP.
