week 3 (brain structure) Flashcards
What is the anterior view?
The front view of the brain
What is the dorsal view?
the view of the brain from the top
What is the posterior view
The view of the brain from the back
What is the ventral view
The view of the brain from the bottom
List all the lobes of the brain and where they are
Frontal (front), Parietal, (middle top), occipital (back) temporal (bottom)
What is the midbrain bundle?
The middle of the brain, connected to forebrain. filled with the ‘leftover’ stuff not taken up by the forebrain or hindbrain lol
What is the forebrain bundle?
Sits above the midbrain in the cebral cortex. cerebrum, thalamus, hypothalamus, pituitary gland, limbic system, and the olfactory bulb
What is the hindbrain bundle.
The cerebrum stuff, the medulla, pons, cranial nerves too
Limbic system
Amygdala and hippocampus. Probably memory and our nervous system
What is the Cerebral cortex:
The cauliflower brian bit we see, goes about 7-20mm deep. The division between the two hemipsheres is called the longitiduinal fissures.
What are granula cells?
Sensory neurons
What are agranula cells
motor neurons
What is retinotopy?
Retinotopy is the mapping of visual input from the retina to neurons, particularly those neurons within the visual stream–everything is processed upside down
What is tonotopy
How audio is mapped (
What is somotopy
How touch is mapped (along cyngulate gyrus)
What is the association cortex?
How everything in the brain links together and communicates. Split into unimodal (where one type of sensory neuron is integrated) or hetermodal/multimodal, where numerous areas are brought together to work (such as when you go to reach for something, you use your vision and motor skills to grab it.)
What behaviours are involved with Executive functioning
Complicated cognitive behaviours . Planning, problem solving, personality
What is Agnosia
When the sense is intact but is unable to connect it to other parts of the brina (eg memory) that make it work .
What is Aphasia
The loss of representation, like symbols or language
What is brocas aphasia?
They understand language, but struggle to speak it.
Wernickes aphasia
Can speak, but its nonsense
Visual agnosia
When someone can see an object, but cannot recognise it–perception without meaning(damage to temporal lobe)
Prospoganosia
Inability to recognise faces. They can see the faces, but cannot retain them from one minute to the next. even family members.
Blindsight
When people have a blindspot in their vision du e to damage to primary visual area. Bilateral damage is when someone is comepletely blind
Neglect/hemispatial neglect
Neglect syndrome is when a patient has damage to the right side of their brain, so ‘ignores’ the left side of everything, even though they can see it. They just don’t pay attention to it. The lady drawing daisys
