Brain Flashcards
The posterior part of the cerebral hemisphere is
Sensory
The anterior part of the cerebral hemisphere is
Motor
What does the Limbic System do
Storage and retrieval of processed information
Area 4 of the brain is also known as
Precentral Gyrus/Primary Motor Cortex
The Inferior Frontal Gyrus is also known as
Broca’s Area of Motor Speech
The prefrontal cortex is involved in
Cognitive Functions of Higher Order Intellect, Judgement, Prediction and Planning
The Frontal Lobe of the brain is
Motor
The Parietal Lobe of the brain is
Somatosensory
The postcentral gyrus is also known as
Primary Sensory Area
Areas 1,2 and 3 are also known as
Postcentral Gyrus/Post Sensory Area
The inferior parietal lobe contributes to
Language Functions
A parietal lobe lesion can lead to
Hemisensory Neglect
The Temporal Lobe is involved in
Hearing and Smell
Superior Temporal Gyrus is also known as
Primary Auditory Cortex/Area 41,42
The Auditory Association Area is also known as
Wernicke’s Area
The inferior surface of the brain receives fibres from
Olfactory Tract
The occipital lobe is involved in
Vision
On the medial surface of the occipital lobe on either side of the calcarine sulcus is the
Primary Visual Cortex (Area 17)
Area 18 and 19 on the occipital lobe are the
Visual Association Cortex
Broca’s area is also known as
Motor Speech Area
Wernicke’s Area is also known as
Auditory Association Area
What is Aphasia
problem with speech due to damage to one or more speech areas in brain
If a patient
- Understands Speech
- Misses small words
- Aware of difficulties in speech
Where is the damage?
Frontal Lobe due to Broca’s Aphasia
If a patient has
- Fluent Speech
- New Meaningless Words
- Can’t understand Speech
- Doesn’t recognise mistakes
Where is the damage
Temporal Lobe due to Wernicke’s Aphasia
