EPSPs produced by many different presynaptic fibers converging on a single postsynaptic neuron causing summation on the postsynaptic dendrites and cell body best describes?
spatial summation
How do nerve impulses travel along neurons?
Point to point or saltatory conduction.
What is the difference between the way excitatory and inhibitory transmitters work?
As a rule more than one presynaptic action potential is needed to fire the postsynaptic neuron or muscle so that the trigger to initiate an action potential are either many subthreshold local potentials from different sources or from the same neuron received within a short period of time. The first case is called spatial summation and the second case is called temporal summation. Whether a postsynaptic potential (another term for a local potential) is excitatory or inhibitory depends on what ion channels are affected by the transmitter released from the presynaptic vesicles.
What increases the amount of information a neuron can receive?
There are different types of receptors, which allow neurons to receive information. In nose you have chemoreceptors. In eyes you have photoreceptor. In the ears you have hair cells of different length, which resonates with sounds of different frequency. On the surface of the tongue you have again chemoreceptors. In the skin you have different types of receptors to give you information like heat, cold, pain, touch and vibration sense.
Functions of synapse?
unidirectional transmissionSignals pass from presynaptic to postsynaptic neurone since: synaptic vesicles are only found in presynaptic neurone and receptors for neurotransmitter are only found in postsynaptic neurone.intterconnection between nerve pathwaysOne neurone may receive signal from many synapses from different presnaptic neurones. This allows a wide range of actions in response to a stimulus.memory and learningNeurones involved are linked by new synapses.
Can two different equipotential surface intersect?
Doesn't seem like they can. If they could, then that would put two different potentials along the intersection.
Where animism was founded?
Developed simultaneously in different parts of the world
Are the stages of mitosis occurs simultaneously on a meristem?
No, they cannot happen simultaneously because each cell undergo different stage of mitosis.
Do action and reaction forces act in succession or simultaneously?
Simultaneously, you can't pull on something unless it simultaneously, pulls back on you.
How is Cubism remembered?
As a revolutionary attempt to view a subject from different viewpoints simultaneously.
Simultaneously processing different aspects of a problem or scene is known as?
parallel processing
What happens when 2 different users try to answer the same question simultaneously?
Nothing
