Olfactory sulcus

The olfactory fissure is a grooved depression in the middle part of the frontal lobe of the brain. It is one of the largest branches of the forebrain and passes between the ventricle and the septum pellucidum. The grooves provide communication from one hemisphere to the other, as well as the formation of grooves.

Passing along the lower surface of the frontal angle of the bone of the base of the skull, it opens into the large sella turcica. The frontal lobe of the brain is located opposite the parietal lobule. This allows the olfactory sulcus to navigate the environment by odors. Ultimately, the groove ensures proper perception of odors thanks to the taste buds on the tongue.

The olfactory fissure also plays a role in regulating mood, sleep, attention and memory. By acting on the cerebral cortex, it can change the biological response to the environment. And in fact, research confirms that the absence or damage of the olfactory center can lead to impaired perception of smells. In addition, the presence of a straight olfactory fissure may be a sign of the presence of certain mental illnesses, such as sensory processing disorders or abnormalities of the limbic system.

Thus, the olfactory sulcus plays an important role in processing sensory information and controlling mood. However, its damage
