LONG TERM DEPRESSION & POTENTIATION

LONG TERM DEPRESSION

• In neurophysiology, LTD is a reduction in the efficiency of neuronal synapses
• They last an hour or longer
• LTD occurs in many areas of the Central Nerv. System
• Usually found in the hippocampus
• Neuronal adjustment to have less of a reaction

LTD EXAMPLE

• Tolerance towards something
• I.E. Putting in contacts, endurance, being out of shape, insulin shots
• Become tolerant to certain stimuli

LONG TERM POTENTIATION

• Long lasting strengthening of a post synaptic nerve cell
• Thought to be related to learning
• Causes a quicker reaction
• Found in hippocampus

LTP

• Your brain gets used to senses
• Each time you see the familiar thing your brain requires less stimulation
• When at first you needed to count 2+2=4, now it comes almost reflexively

LTP

• Each time NT's cross synapse, cause neuron memory
• Causes greater stimuli

LTD VS LTP

• LTD is REDUCTION in efficiency of neuronal synapses
• LTP is INCREASE in the efficiency of neuronal synapses
