WebbThe primary olfactory area consists of numerous cortical and subcortical regions of the brain, including the anterior olfactory nucleus, the piriform cortex (posterior orbitofrontal cortex; stocktickerOFC), parts of the amygdala, the olfactory tubercle, the frontal and temporal piriform cortices, etc. (Doty, 2009; Zhou et al., 2024; Cersosimo ... Webbafter the cortical injury [54]. The piriform cortex (PC) is part of the olfactory cortex involved in the sense of smell; a fundamental sense that warns animals of the dangers or the possibility of satisfying appetites such as thirst, hunger or sex [55,56]. Smell also triggers some behaviors such as feeding or defense [57].
WebbFor example, in rodents, piriform cortex–mediodorsal thalamic nucleus functional connectivity is reduced during slow-wave state compared to waking (Courtiol and Wilson, 2014) which may alter this indirect information flow between the piriform cortex and orbitofrontal cortex, while leaving direct piriform cortical—orbitofrontal cortex … Webb17 mars 2024 · Feedforward inhibitory circuits are key contributors to the complex interplay between excitation and inhibition in the brain.
