Brain. Sac 2

Frontal lobe

Plays a role in planning, arranging and executing voluntary movement. Also in higher level functions like decision making and working memory.

what are the 3 cortexes in the frontal lobe and what do they do?

Prefrontal cortex- involved in planning movement, reasoning, problem solving, attention.

Premotor cortex- prepares and then sends information on the planned motor sequence to Primary cortex.

Primary cortex- Responsible for initiating and executing the sequence by sending neural messages to muscles.

Broca’s area

Located in the left hemisphere’s frontal lobe. Plays role in producing clear and fluent speech. Also sends and receives messages regarding language.

Temporal lobe

receives and processes sounds. Also plays a role in memory, emotional responses and recognising faces.

Primary auditory cortex

Located in the temporal lobe. Assists in responding and identifying sounds.

Wernicke’s areas

Located in temporal lobe. Has critical role in understanding sounds involved in speech.

Parietal lobe

Involved in attention, spatial awareness and reasoning. Also receives and processes somatosensory info

Primary somatosensory cortex

located front of parietal lobe. receives and processes somatosensory information (sensations of touch pain and temperature)

Occipital lobe

Plays a role in vision by receiving and computing visual info

Primary visual cortex

receives and processes information from receptors in the eyes’ retina.

Contralateral control

Each hemisphere of the brain controls the opposite side of the body. All cortexes in the lobes do this
