The Brain + The Cerebral Cortex
The Frontal Lobe
Brocas Area
Named after Paul Broca
Broca’s area directs the area of the primary motor cortex
Broca's area is principally in charge of producing articulate (clear) speech by controlling the movement of these muscles. It also helps with sentence structure and grammar analysis.
The Primary Motor Cortex
Area that provides the most important signal for the production of skilled movements. Electrical stimulation of this area results in focal movements of muscle groups on the opposite side of the body, depending on the area stimulated.
Functions of the Frontal Lobe
Complex mental abilities and voluntary movement control.
Planning, problem-solving, thinking, memorising, learning, and analysing are some of our most complicated mental behaviours.
Controls voluntary movement.
It contains the main motor cortex, which controls voluntary movement by directing the body's skeletal muscles.
The Occipital Lobe
Primary Visual Cortex
A variety of neurones in the primary visual cortex are specialised to respond to certain aspects of visual input. For example, some are for colour, others are for shape, and some are for motion.
It is the brains primary visual area. This is a region at the base of the occipital lobe that records and processes visual input from both eyes' retinas.
The optic nerves are linked to neurones in the visual cortex.
The Temporal Lobe
Wernickes Area
Identified by Carl Wernicke and in 95% of people found in the left temporal lobe, and in the right for the other 5%)
Wernicke’s area is located near the primary auditory cortex, and it is connected to Broca’s area by nerve fibres.
It is believed to be responsible for accessing words stored in memory; therefore, it is believed to be responsible for the comprehension of speech and the formulation of meaningful sentences.
Auditory (sound-based) information received by both ears is transmitted directly to each temporal lobe, making them the main site where hearing registers.
Contain the primary auditory cortex.
The right temporal lobe is specialised to process non-verbal sounds (for example, the sound of a siren or a door slamming).
The Parietal Lobe
The primary somatosensory cortex is adjacent to the primary motor cortex.
Sensations detected in the sensory receptors located throughout the body and the skin are registered and processed in the primary somatosensory cortex.
As a result, we feel a sensation and form a perception of what it is and where it came from.
Mostly associated with processing bodily sensations.
Touch, Temperature, pressure and other sensation relating to muscle and joint movement and the body's position in space are registered in the parietal lobes primary somatosensory.
