The primary olfactory cortex is in the inferior part of the temporal lobe of the brain. [1] It involves the anterior olfactory nucleus, [2] the piriform cortex, [2] the olfactory tubercle, [2] part of the amygdala, [2] part of the entorhinal cortex, [2] [3] and the periamygdaloid cortex. [2] [4] Some sources state that it also includes the ...
In human anatomy, the piriform cortex has been described as consisting of the cortical amygdala, uncus, and anterior parahippocampal gyrus. [1] More specifically, the human piriform cortex is located between the insula and the temporal lobe, anteriorly and laterally of the amygdala. [2] [3]
The uncus houses the olfactory cortex which includes the piriform cortex (posterior orbitofrontal cortex), amygdala, olfactory tubercle, and parahippocampal gyrus. The olfactory tubercle connects to numerous areas of the amygdala, thalamus, hypothalamus, hippocampus, brain stem, retina, auditory cortex, and olfactory system. In total it has 27 ...
The sensory cortex can refer sometimes to the primary somatosensory cortex, or it can be used as a term for the primary and secondary cortices of the different senses (two cortices each, on left and right hemisphere): the visual cortex on the occipital lobes, the auditory cortex on the temporal lobes, the primary olfactory cortex on the uncus of the piriform region of the temporal lobes, the ...
Using anterograde tracing methods, Cenquizca and Swanson (2007) located the moderate projections to two primary olfactory cortical areas and prelimbic areas of the medial prefrontal cortex. This region has the smallest number of place cells. The ventral hippocampus functions in fear conditioning and affective processes. [38]
Located in the temporal lobe, the primary olfactory cortex is the primary receptive area for olfaction, or smell. Unique to the olfactory and gustatory systems, at least in mammals , is the implementation of both peripheral and central mechanisms of action.
The anterior olfactory nucleus (AON) also called the anterior olfactory cortex, is a portion of the vertebrate forebrain. It is involved in the sense of smell (olfaction), and has influence on other olfactory areas including the olfactory bulb and the piriform cortex. [1] [2] The AON is one of the major secondary structures of olfaction. [3]
The insular cortex is a portion of the cerebral cortex folded deep within the lateral sulcus (the fissure separating the temporal lobe from the parietal and frontal lobes). The insular cortex has an important function for sending axons to the amygdala and responding to tones and somatosensory stimulation. [12]
