The cell bodies of invertebrate unipolar neurons are often located around the edges of the neuropil, in the so-called cell-body rind. [3] Most neurons in the central nervous systems of vertebrates, including mammals, are multipolar. [4] In multipolar neurons, multiple processes extend from the cell body including dendrites and axons.
Bipolar neurons exist within the vestibular nerve as it is responsible for special sensory sensations including hearing, equilibrium and motion detection. The majority of the bipolar neurons belonging to the vestibular nerve exist within the vestibular ganglion with axons extending into the maculae of utricle and saccule as well as into the ...
Bipolar disorder is difficult to diagnose. [2] If a person displays some symptoms of bipolar disorder but not others, the clinician may diagnose bipolar NOS. The diagnosis of bipolar NOS is indicated when there is a rapid change (days) between manic and depressive symptoms and can also include recurring episodes of hypomania. Bipolar NOS may be ...
Bipolar cells receive synaptic input from either rods or cones, or both rods and cones, though they are generally designated rod bipolar or cone bipolar cells. There are roughly 10 distinct forms of cone bipolar cells, however, only one rod bipolar cell, due to the rod receptor arriving later in the evolutionary history than the cone receptor ...
The five basic classes of neurons within the retina are photoreceptor cells, bipolar cells, ganglion cells, horizontal cells, and amacrine cells. The basic circuitry of the retina incorporates a three-neuron chain consisting of the photoreceptor (either a rod or cone), bipolar cell, and the ganglion cell. The first action potential occurs in ...
Pyramidal cells, or pyramidal neurons, are a type of multipolar neuron found in areas of the brain including the cerebral cortex, the hippocampus, and the amygdala. Pyramidal cells are the primary excitation units of the mammalian prefrontal cortex and the corticospinal tract.
A multipolar neuron is a type of neuron that possesses a single axon and many dendrites (and dendritic branches), allowing for the integration of a great deal of information from other neurons. These processes are projections from the neuron cell body. Multipolar neurons constitute the majority of neurons in the central nervous system.
The sgACC volume is observed to be reduced not only in bipolar disorder, but also in unipolar disorder, as well as people with a family history of affective disorders. Enlargement of the striatum and globus pallidus are commonly found, and although some studies fail to observe this, at least one study has reported no volumetric but subtle ...
