Understanding the brain Flashcards
Neuroscientist:
A scientist that specializes in the study of the human brain
Phineas Gage Accident
Phineas Gage was a 25-year-old construction worker. in 1848, he accidentally set off an explosive that propelled a rod through his left cheek and out o his skull. this was the first case that demonstrated the relationship between brain and behaviour
Cerebrum
The brain’s problem-solving ability is controlled by the cerebrum, that is divided into two hemispheres
Cerebral Cortex
It is covering the whole brain and is made of grey matter
Left hemisphere
It is responsible for communication and language, logic, mathematical abilities
Right Hemisphere
This site receives and analyzes information, and is responsible for facial recognition, spatial awareness, and visual imagery
Corpus Callosum
The two hemispheres in your brain are connected by a thick bundle of nerve fibres called the corpus callosum that ensures both sides of the brain can communicate and send signals to each other.
Frontal Lobe
Involved in speaking and planning actions
Executive functions refer to a collection of cognitive skills including the capacity to plan, organise, initiate, self-monitor and control one’s responses in order to achieve a goal.
Temporal Lobe
Analyzes sounds to make sense of speech
Hippocampus
Responsible for short term and long term memory, it is also a part of the emotional system which stores the name of people and things.
Amygdala
They are two almond-shaped neural clusters that regulate how emotion can affect memory, and they create fight or flight in response to fear and danger.
Parietal Lobe
It processes sensory information it receives from the outside world, mainly relating to touch, taste, and temperature.
Occipital Lobe
The occipital lobe is the visual processing center of the mammalian brain (responsible for vision)
Perception:
The process of selecting, organizing, and interpreting our sensations.
the ability to see, hear, or become aware of something through the senses.
Closure
The principle of closure happens when the information given to the brain is incomplete, so the brain fills out the missing information
