What determines whether a postsynaptic potential will be either excitatory or inhibitory?
What determines whether a postsynaptic potential will be either excitatory or inhibitory?
What determines whether a post synaptic potential will be either excitatory or inhibitory? Both EPSPs and IPSPs are the result of the release of transmitter from a pre-synaptic cell. The type of ion entering the cell usually determines whether it will be excitatory or inhibitory.
What is the difference between a presynaptic neuron and a postsynaptic neuron?
Anatomically, the presynaptic neuron is the neuron before the synapse, this neuron is delivering the “message” across the synapse to the postsynaptic neuron. The postsynaptic neuron is the “receiver” of the neurotransmitter “message”.
How do neurons integrate information?
Essentially all neurons receive input signals, integrate those signals, transmit information over distances, and communicate with target cells via release of neurotransmitters. The receiving and integrating compartment in most neurons is made up of dendrites and cell bodies.
Do Neurons receive information?
The dendrites of neurons receive information from sensory receptors or other neurons. This information is then passed down to the cell body and on to the axon. Once the information has arrived at the axon, it travels down the length of the axon in the form of an electrical signal known as an action potential.
What is the function of neurons and synapses?
Synapses are essential to the transmission of nervous impulses from one neuron to another. Neurons are specialized to pass signals to individual target cells, and synapses are the means by which they do so.
Is a 120 IQ good?
An IQ score of 115 means performance one standard deviation above the median, a score of 85 performance, one standard deviation below the median, and so on….Stanford–Binet Intelligence Scale Fifth Edition.
