patterns of the upper motor neurons. The cerebellum receives its input from the spinal cord in form of mossy fibers that project from the pons and spinocerebellar pathways. Mossy fibers contribute the information necessary for the output from the motor cortex and sensory information about the state of the body. In addition, it also receives input from climbing fibers that project from the inferior olive, of which contribute information about the errors in movement. These climbing…

Anatomy of cerebral cortex: Brain is most complex organ in human body. The ability of brain for its functioning normally is manifestation of various activities it takes participation in various activities of day to day life, being it hidden from the view or perceptible, like walking, smelling, thinking, laughing, speaking, and hearing.

human behavior is linked, somehow or someway, to the brain’s functions. According to the beliefs of these psychologists, each area of the brain influences different thinking and behavior.

Broca’s area controls the production of speech and Wernicke’s area controls the comprehension of speech. Apart from the individual roles parts of the brain play, one’s behavior is also linked to the…

stabilise the joint (Schultz RA et al1984). Injuries, including ACL tears, are likely to disrupt this process. Spinal motor neuron receives afferent information from both ipsilateral and contralateral limbs (Cuadrado ML et al 1999). In the cerebral motor cortex cross-connections between…
