Most patients with schizophrenia demonstrate a lower level of frontal lobe activity than healthy control participants. why would
Makovka662 [10]

The frontal lobe has, as some of its functions, the capability to project possible consequences as a result of current actions leading to the choice between worse and better actions, as well as the ability to give importance or suppress socially unacceptable responses. It is also important when it comes to integrating memories associated with emotions, where the frontal lobe use them to fit socially acceptable norms.

These are all functions that are affected in patients with schizophrenia, explaining why there is lower activity at the frontal lobe on them than on those of the healthy control which had normal levels of activity.

Summation that results from the cumulative effect of multiple synapses at multiple places on the neuron is designated.
Effectus [21]

Summation that results from the cumulative effect of multiple synapses at multiple places on the neuron is designated spatial summation.

  • A strategy for generating an action potential in a neuron using input from several presynaptic cells is called spatial summation. It is the algebraic addition of potentials from various input regions, typically dendrites.
  • This process, known as spatial summation, occurs when inputs from several neurons combine to cause an action potential. These potentials, which are often from dendrites, are combined to produce the spatial summation.
  • The likelihood that a potential will reach the threshold level required to trigger an action potential increases with the amount of excitatory postsynaptic potentials.
  • Similar to this, the likelihood of attaining the threshold potential to trigger an action potential decreases as the number of inhibitory postsynaptic potentials increases.
