In neuroanatomy, a sulcus (Latin: "furrow"; pl.: sulci) is a shallow depression or groove in the cerebral cortex.One or more sulci surround a gyrus (pl. gyri), a ridge on the surface of the cortex, creating the characteristic folded appearance of the brain in humans and most other mammals.
When something else is wrong, that drains your body’s resources needed to sustain normal brain functions, Charvet explains. Other suspected causes or triggers of brain fog include: Certain ...
On the nasal surface of the body of the maxilla, in front of the opening of the sinus is a deep groove, the lacrimal groove (or lacrimal sulcus), which is converted into the nasolacrimal canal, by the lacrimal bone and inferior nasal concha; this canal opens into the inferior meatus of the nose and transmits the nasolacrimal duct.
Brain fog is a common symptom in many illnesses where chronic pain is a major component. [26] Brain fog affects 15% to 40% of those with chronic pain as their major illness. [27] In such illnesses, pain processing may use up resources, decreasing the brain's ability to think effectively. [26]
This underlying cause is reversible if you quit the meds, but other reversible causes might not be so obvious. Depression or major stress could cause impairment to show up in testing, too, Boyle says.

The parietal lobe is positioned above the occipital lobe and behind the frontal lobe and central sulcus.. The parietal lobe integrates sensory information among various modalities, including spatial sense and navigation (proprioception), the main sensory receptive area for the sense of touch (mechanoreception) in the somatosensory cortex which is just posterior to the central sulcus in the ...
There is a region of the central sulcus, called the “hand knob”, which is a notch in the area of the hand motor region. The position of this “knob” can be indicative as well of someone's handedness. [11] As motor functions develop, it is expected that the shape of the central sulcus will change.
