The occipital lobes sit at the back of the head and are responsible for visual perception, including colour, form and motion. Damage to the occipital lobe can include: Difficulty with locating objects in environment. Difficulty with identifying colours (Colour Agnosia) Production of hallucinations.
What is the primary role of the occipital lobe?
The occipital lobe is the seat of most of the brain’s visual cortex, allowing you not only to see and process stimuli from the external world, but also to assign meaning to and remember visual perceptions.
How does the occipital lobe affect behavior?
Injury to the occipital lobes may lead to vision impairments such as blindness or blind spots; visual distortions and visual inattention. The occipital lobes are also associated with various behaviors and functions that include: visual recognition; visual attention; and spatial analysis.
What are 3 functions of the occipital lobe?
Below is a list of some of the associated functions of the occipital lobes: Assessing size, depth, and distance Determining color information. Object recognition.
What is occipital lobes in psychology? – Related Questions
What lobes are responsible for personality?
The frontal lobes are considered our behaviour and emotional control centre and home to our personality. There is no other part of the brain where lesions can cause such a wide variety of symptoms.
What part of the brain affects behavior?
Prefrontal Cortex – The term prefrontal cortex refers to the very front part of the brain located behind the forehead and above the eyes. It appears to play a critical role in the regulation of emotion and behavior by anticipating the consequences of our actions and inhibiting behaviors.
How might damage to the frontal and occipital lobes of the brain impact behavior?
Damage to the neurons or tissue of the frontal lobe can lead to personality changes, difficulty concentrating or planning, and impulsivity.
What will happen if the occipital lobe is damaged?
An injury to the occipital lobes can lead to visual field cuts, difficulty seeing objects or colors, hallucinations, blindness, inability to recognize written words, reading or writing, inability to see objects moving, and poor processing of visual information.
What happens when the occipital lobe is stimulated?
WHEN THE visual cortex in the occipital lobe is electrically stimulated, human subjects see circumscribed and often punctate sensations of light, called phosphenes.
How does anxiety affect the occipital lobe?
In addition, the occipital lobe was associated with face recognition, sensitivity to fearful stimuli, emotion processing and levels of trait anxiety [94,95]. The worry also seemed to decrease regional blood flow in occipital lobe, which confirmed the role of occipital lobe in the worry model for PD [96].
What symptoms would you see in someone whose occipital lobe has been damaged?
Located at the back of the brain, the occipital lobes are responsible for visual perception. Damage to them results in loss of visual capability, an inability to identify colors, and hallucinations. At times, patients experience severe vision loss or total blindness.
What part of the brain controls memory?
A curved seahorse-shaped organ on the underside of each temporal lobe, the hippocampus is part of a larger structure called the hippocampal formation. It supports memory, learning, navigation and perception of space. It receives information from the cerebral cortex and may play a role in Alzheimer’s disease.
Where is trauma stored in the brain?
When a person experiences a traumatic event, adrenaline rushes through the body and the memory is imprinted into the amygdala, which is part of the limbic system. The amygdala holds the emotional significance of the event, including the intensity and impulse of emotion.
What part of the brain controls fear?
Many of their studies begin with the amygdala, an almond-shaped structure that is considered the hub for fear processing in the brain.
What part of the brain controls balance and walking?
The Cerebellum
This area of the brain is responsible for fine motor movement, balance, and the brain’s ability to determine limb position. A stroke in this area of the brain can lead to paralysis or “jerky” muscle movements.
What part of the brain is responsible for happiness?
Neuroscience studies showed that some part of brain (e.g. amygdala, hipocamp and limbic system) and neurotransmitters (e.g. dopamine, serotonin, norepinefrine and endorphin) play a role in control of happiness.
What part of the brain is problem solving?
The frontal lobe is responsible for initiating and coordinating motor movements; higher cognitive skills, such as problem solving, thinking, planning, and organizing; and for many aspects of personality and emotional makeup.
What part of the brain controls the activity of walking without failing?
The cerebellum sits at the base of the brain and receives nerve signals reporting balance from all over the body. It is the junction box to and from the brain for all movement and co-ordination.
What part of the brain controls heartbeat and blood pressure?
The brain stem sits beneath your cerebrum in front of your cerebellum. It connects the brain to the spinal cord and controls automatic functions such as breathing, digestion, heart rate and blood pressure.
