Sensory cortex
In this article, we will delve into the fascinating world of Sensory cortex, exploring its origins, impact and relevance today. From its emergence to its influence in various spheres of society, Sensory cortex has played a fundamental role in shaping our world. Throughout this detailed analysis, we will examine its most relevant aspects, as well as the controversies and debates it has raised over time. From its impact on popular culture to its influence on politics and the economy, Sensory cortex has positioned itself as a topic of unavoidable interest in contemporary discourse. Join us on this journey of discovery and reflection about Sensory cortex, to better understand its importance and significance in our society.
The sensory cortex can refer informally 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 gustatory cortex on the insular lobe (also referred to as the insular cortex), and the primary somatosensory cortex on the anterior parietal lobes. Just posterior to the primary somatosensory cortex lies the somatosensory association cortex, which integrates sensory information from the primary somatosensory cortex (temperature, pressure, etc.) to construct an understanding of the object being felt. Inferior to the frontal lobes are found the olfactory bulbs, which receive sensory input from the olfactory nerves and route those signals throughout the brain. Not all olfactory information is routed to the olfactory cortex: some neural fibers are routed to the supraorbital region of the frontal lobe, while others are routed directly to limbic structures. The direct limbic connection makes the olfactory sense unique.
The brain cortical regions are related to the auditory, visual, olfactory, and somatosensory (touch, proprioception) sensations, which are located lateral to the lateral fissure and posterior to the central sulcus, that is, more toward the back of the brain. The cortical region related to gustatory sensation is located anterior to the central sulcus.
Note that the central sulcus (sometimes referred to as the central fissure) divides the primary motor cortex (on the precentral gyrus of the posterior frontal lobe) from the primary somatosensory cortex (on the postcentral gyrus of the anterior parietal lobe).
The sensory cortex is involved in somatic sensation, visual stimuli, and movement planning.
