dopamine appear to influence activity in different areas of the brain so that abnormalities can cause abnormal activities in certain parts of the brain. Importantly for schizophrenia‚ dopamine appears to play a big role in the activity in the frontal and temporal lobes of the brain. The regions that play essential roles in the cognitive‚ perceptual‚ and emotional functions that are often abnormal in schizophrenia. Supporting the idea that abnormalities of dopamine may be playing a role in schizophrenia

Medulla A structure of the brain stem that is responsible for automatic bodily functions‚ such as breathing and heart rate. 3. Reticular Activating System The RAS screens incoming information and arouses the cortex when something happens that requires their attention. 4. Cerebellum The cerebellum functions as a "lesser brain" It contributes

also divided into lobes – the frontal‚ parietal‚ occipital‚ and temporal lobes. The frontal lobe is responsible for voluntary muscle movement‚ emotional reactions and expressions. In the parietal lobe on the other hand‚ positioned posterior to the frontal lobe‚ its responsible for the integrating sensory information from the various parts of the body. In other words‚ it helps us process touch and taste. Next is the occipital lobe‚ located posterior to the temporal and parietal lobes. This is the brain’s

cortex has four lobes – the frontal lobe‚ the parietal lobe‚ temporal lobe‚ and the occipital lobe (“Brain Structures and their Functions‚” n.d.; “Frontal Lobe - The Brain Made Simple‚” n.d.). The frontal lobe performs executive functions. These functions include initiation‚ inhibition‚ purposive action‚ volition‚ planning‚ reasoning‚ problem solving‚ parts of speech‚ flexibility‚ self-monitoring and self-regulation. It is used in making decisions and thinking. The frontal lobes are needed to complete

different lobes. The temporal‚ frontal‚ parietal‚ and occipital lobes control a variety of cognitive functions (Santrock‚ 2013). The brain controls simple functions such as fine and gross motor skills‚ vision‚ and memory. For instance the frontal lobes are involved in the voluntary movement‚ thinking‚ personality‚ and intentionality or purpose. The occipital lobes are responsible for vision. The temporal lobes are responsible for hearing‚ language processing and memory. The parietal lobes plays role

1. Brainstem- It begins where the spinal cord swells after entering the skull. It regulates all automatic survival roles‚ such as breathing and heartbeats. 2. Thalamus- The thalamus is the uppermost part of the brainstem. It directs information to the sensory cortex and provides feedback to the cerebellum and medulla. 3. Medulla- The foundation of the brainstem. It manages heartbeat and breathing. 4. Reticular formation- The nerve region travelling through the brainstem and thalamus. The network

Semantic-associative This type of auditory agnosia is caused by lesions to the left hemisphere of the brain‚ specifically the temporal lobes and Wernicke’s area. Linguistic (or verbal information or Wernicke’s) agnosia indicates that the subject can’t comprehend words‚ although they can understand words
