The brain Flashcards
The cerebral cortex
Made up of Gray matter which consist of neuronal cell bodies Which play key roles in many of the higher functions that make us human
What does the cerebral cortex consist of ?
Frontal lobe
Parietal lobe
Occipital lobe
Temporal lobe
What is the frontal lobe responsible for ?
Controls movement
Higher cognitive skills and mental skills
Organising information
Planning and decision making
Problem solving
Expression of personality
Reasoning
Making judgements
Consists primary motor cortex responsible for movement iniates voluntary muscle movement and integrates activities of skeletal muscles
What is the Broca’s area and how does it relate to the frontal lobe ?
to organise speed production
Directs the muscle movement via motor cortex responsible for the production of articulate speech
Allows for the production of all forms of language
What is broca’s Aphasia ?
Speech impairment caused by brain damage to the Broca’s area nonfluent aphasia communication slow and awkward including speech,signing,writing
Speech is meaningful know what to say but are unable to produce the word they want to sat
What happens if there is damage to the parietal lobe ?
damage results in problems with spatial awareness, coordination and as well as sensation
What is the parietal lobe responsible for ?
Senses
Processes sensory stimuli
Ability to orient the body in space
Responsible for the recognition of self
Responsible for the recognition of your body and its parts
Includes the somatosensory cortex which responsible for transforming sensation into meaning, representation of all body parts
Damage in this lobe causes blind spots, difficultly recognising objects and an inability to identify colour and trouble recognising words
Occipital lobe
Responsible for processing visual information form the eyes
- visual perception
-visual processing
- interpreting visual stimuli
Primary visual cortex
Present in the occipital lobe registers and process and interprets visual information sent form each eye
Temporal lobe
Process auditory information
Involved in memory
Contribute to complex aspects of vision including facial recognition and movement
Involved in emotional and notional behaviours
Primary auditory cortex
Area of the Brain’s temporal lobe that registers and processes auditory information
Wernicke’s area
Allows for the comprehension of language
Area of the left temporal lobe responsible for the comprehension of language and formulation of meaningful sentences
Wernicke’s aphasia
Unaware the words being produced are incorrect and non-sensical
May have severe comprehensions difficulties
May be unable to grasp the meaning of spoken words but may be able to produce fluent and connected speech
