The mental nerve is a sensory nerve of the face. It is a branch of the posterior trunk of the inferior alveolar nerve, itself a branch of the mandibular nerve (CN V 3), itself a branch of the trigeminal nerve (CN V). It provides sensation to the front of the chin and the lower lip, as well as the gums of the anterior mandibular (lower) teeth.
The cranial region includes the upper part of the head while the; facial region includes the lower half of the head beginning below the ears. The forehead is referred to as the frontal region. The eyes are referred to as the orbital or ocular region. The cheeks are referred to as the buccal region. The ears are referred to as the auricle or ...
Robinson (1913) [3] suggests that the demand to resist masticatory stresses triggered bone thickening in the mental region of the mandible and ultimately formed a prominent chin. Moreover, Daegling (1993) [ 4 ] explains the chin as a functional adaptation to resist masticatory stress that causes vertical bending stresses in the coronal plane .
Typically, participants will view different kinds of face stimuli which can be contrasted with scrambled images, letter strings or non-face objects to localise the OFA. [ 3 ] [ 4 ] [ 5 ] While the exact location of the OFA varies between individuals and depands on the specific paradigm used, it usually corresponds to Brodmann areas 18 or 19 . [ 6 ]
This suggests that the basal ganglia work in both encoding and recalling spatial information. People with Parkinson's disease display working memory impairment during sequence tasks and tasks involving events in time. They also have difficulty in knowing how to use their memory, such as when to change strategies or maintain a train of thought. [25]

The facial skeleton comprises the facial bones that may attach to build a portion of the skull. [1] The remainder of the skull is the neurocranium.. In human anatomy and development, the facial skeleton is sometimes called the membranous viscerocranium, which comprises the mandible and dermatocranial elements that are not part of the braincase.
The case helped to convince people that mental functions were localised in the brain. [208] The philosophy of the mind studies such issues as the problem of understanding consciousness and the mind–body problem. The relationship between the brain and the mind is a significant challenge both philosophically and scientifically.
