It is located behind the central sulcus, and above the occipital lobe. Functions of the parietal lobe include information processing, movement, spatial orientation, speech, visual perception, recognition, perception of stimuli, pain and touch sensation, and cognition. The optic nerves passes through the parietal lobe to the occipital lobe. The parietal lobe is responsible for integrating sensory information from various parts of the body. Increased susceptibility to distractions.Impaired spontaneity and mental flexibility.Reduced or no sense of taste and/or smell.Reduced sexual interest or peculiar sexual habits.Increased or decreased problem-solving ability and creativity.Any damage to this lobe of the brain can lead to one or more of the following problems. The frontal lobe is extremely vulnerable to injury due to its location, as it is in front of the central cranium. The anterior portion is responsible for higher cognitive functions, and the posterior portion consists of the premotor and motor areas, thus, governing voluntary movements. The frontal lobe is separated from the parietal lobe by the central sulcus. Functions of the frontal lobe include reasoning, planning, organizing thoughts, behavior, sexual urges, emotions, problem-solving, judging, organizing parts of speech, and motor skills (movement). The frontal lobe is made up of the anterior portion (prefrontal cortex) and the posterior portion. In human beings, the frontal lobe attains maturity around the age of 25. The frontal lobe is home to our cognitive thinking, and it is this process that determines and shapes an individual’s personality.
