Answer
When presynaptic neurons get activated ,this cause release of glutamate.Glutamate present most widely in brain and central nervous system that participate in major excitatory brain functions.
Glutamate have an important role in neural circuit as it involve in synaptic plasticity(the ability to strengthening or weakening of signaling between neurons).Glutamate is the neurotransmitter which is very fast and pass information processing in neuronal network.Glutamate receptors are available in through out the central nervous system and present in neuron and glial cell also.Glutamate also connected with the activity of other neurotransmitter system.
Which neurons release glutamate? Why is glutamate suitable for the functions of these neurons?
Twenty neurons synapse with a single receptor neuron. Fifteen of the twenty neurons release neurotransmitters that produce EPSPs in the post-synaptic cell, whereas the remaining five neurons release neurotransmitters that produce IPSPs in the post-synaptic cells. When each of the twenty neurons is stimulated, it release enough neurotransmitters to produce a 2mV change (either positive or negative) in the postsynaptic membrane potential. If the threshold of the post-synaptic cell is 10mV greater than its resting potential, how many excitatory neurons...

Describe the following neurotransmitters and explain their functions in the human body giving examples of the disorders associated with them. i. Acetylcholine (ACh) ii. Dopamine iii. Endorphins iv. Glutamate v. Serotonin
Which of the following are NOT true regarding neurotransmitters in the autonomic nervous system? cholinergic neurons release acetylcholine O adrenergic neurons release norepinephrine (noradrenaline) O acetylcholine binds to nicotinic and muscarinic receptors norepinephrine (noradrenaline) binds to alpha and beta adrenergic receptors O only the parasympathetic nervous system releases norepinephrine
Imagine you are studying the activity of neurons in a mouse that is awake and interacting with other mice. If you knew that an excitatory post-synaptic potential (EPSP) occurred, you _______ predict whether it would increase or decrease the likelihood of a particular behavior happening. You do, however, know that the neurons you are studying could be releasing ___________ because it is the major excitatory neurotransmitter in the brain that generally depolarizes postsynaptic neurons. If you wanted to study what...
