Megalencephaly (or macrencephaly; abbreviated MEG) is a growth development disorder in which the brain is abnormally large. It is characterized by a brain with an average weight that is 2.5 standard deviations above the mean of the general population. [2]
In the head, patients exhibit macrocephaly. This is characterized by megalencephaly, which is the enlargement of the brain leading to an increase in the size of the actual head. [3] In the central nervous system, several symptoms are observed. Megalencephaly, the enlargement of the brain, is notable as it represents the "M" in MLC.
In split-brain patients, the corpus callosum is cut, severing the main structure for communication between the two hemispheres. The first modern split-brain patient was a war veteran known as Patient W.J., [10] whose case contributed to further understanding of asymmetry. Brain asymmetry is not unique to humans.
It is about 45 cm (18 in) long in men and around 43 cm (17 in) in women, ovoid-shaped, and is enlarged in the cervical and lumbar regions. The cervical enlargement, located from C3 to T2 spinal segments, is where sensory input comes from and motor output goes to the arms.
If you do have low testosterone, your healthcare provider will test your LH and FSH levels to determine if the root of your low T is in the testicles or the brain (i.e. if you have primary or ...
A neurological examination is the assessment of sensory neuron and motor responses, especially reflexes, to determine whether the nervous system is impaired. This typically includes a physical examination and a review of the patient's medical history, [1] but not deeper investigation such as neuroimaging.
Along with the brain, it develops from the dorsal nerve cord in the embryonic stage. The spinal cord consists of such segmental enlargements called ganglia. These ganglia form the basis for the peripheral nervous system’s (PNS) sensory and motor neurons that innervate various parts of the body.
