What is the difference between EPSP and an IPSP?

An EPSP is an excitatory postsynaptic potential, which represent input coming from excitatory cells, whereas an inhibitory postsynaptic potential represents input driven by inhibitory presynaptic cells.


What type of membrane potential is generated at the synapse on the postsynaptic membrane?

It can be an excitatory postsynaptic potential (EPSP) or an inhibitory postsynaptic potential (IPSP), depending on the synapse. The EPSP depolarizes the membrane, while the IPSP hyperpolarizes it.


What are epsp?

EPSP stands for excitatory postsynaptic potential. It is a temporary depolarization of postsynaptic membrane potential caused by the flow of positively charged ions into the neuron, usually due to the binding of neurotransmitters to their receptors. EPSPs can help to trigger an action potential in the neuron.


How long does an excitatory postsynaptic potential lasts?

An excitatory postsynaptic potential (EPSP) typically lasts for a few milliseconds, ranging from about 10 milliseconds to a maximum of around 50 milliseconds. The duration of an EPSP can vary depending on factors such as the specific neurotransmitter involved, the properties of the receptor, and the activity of ion channels in the postsynaptic neuron.


What will occur when an excitatory postsynaptic potential EPSP is being generated on the dendritic membrane?

A single type of channel will open, permitting simultaneous flow of sodium and potassium.


The effect of a neurotransmitter on the postsynaptic cell occurs when the neurotransmitter?

binds to specific receptors on the postsynaptic cell membrane, leading to changes in the cell's membrane potential. This can either excite or inhibit the postsynaptic neuron, influencing the likelihood of an action potential being generated. Ultimately, the effect of the neurotransmitter can influence the communication between neurons in the nervous system.


What determines if an action potential is initiated in the postsynaptic neuron?

Every time neurotransmitter is released from the presynaptic neuron it generates an excitatory post synaptic potential(EPSP) in the postsynaptic neuron. When the EPSP is greater than the threshold for excitation an action potential is generated.


Why do rods not function effectively in bright light?

Rods produce steady ion flow in the dark that cuases an IPSP that produces no signal in optic nerve. When rod absorbs light, dark current ceases and no inhibiion occurs to EPSP occurs in optic nerve.


When a second EPSP arrives at a single synapse before the effect of the first have disappeared what occurs?

The two EPSPs summate, leading to a higher membrane potential change and increasing the likelihood of an action potential being generated in the postsynaptic neuron. This phenomenon is known as temporal summation.


What determines whether a neuron has an action potential?

A neuron will have an action potential if the stimuli it receives are strong enough to reach its threshold level. Once the threshold is reached, voltage-gated channels open, allowing an influx of sodium ions which triggers depolarization and leads to the generation of an action potential.


How do different societies decide what will be produced by whom will it be produced and for whom will it be produced?

In a free market economy, you the owner gets to chose who it is produced by, how it is produced and what is prdouced. In a command economy, the government chooses how it is produced, who it is produced by and what is produced. A mixed economy is mixed with command and free market.


What ions movement and direction cause epsp?

Excitatory postsynaptic potentials (EPSPs) result from the movement of positively charged ions, typically sodium (Na+) and potassium (K+), into the postsynaptic neuron. This influx of positive charge depolarizes the postsynaptic neuron's membrane potential, making it more likely to fire an action potential.
