The brain Flashcards
What systems is the brain apart of
The central nervous system (CNS)
What is the brain made of
Billions of interconnected neurones
What is the brain in charge of
Running …. behaviours, it c…. and coordinates everything you do
Running complex behaviours, it controls and coordinates everything you do
What are the 5 main parts of the brain
-c
-m
-s
-c
-h
-cerebral cortex
-medulla
-spinal cord
-cerebellum
-hypothalamus
What does the cerebral … do
It’s responsible for things like:
-c
-i
-m
-l
It’s responsible for things like:
-consciousness
-intelligence
-memory
-language
What does the medulla do
It’s responsible for:
-u
Eg b…, h…
It’s responsible for:
-unconscious activities
Eg breathing, heartbeat
What does the cerebellum do
It’s responsible for:
-m… c…
-b
It’s responsible for:
-muscle coordination
-balance
What does the hypothalamus do
Regulates:
-B… t…
-w… b…
Regulates:
-Body temperature
-water balance
3 main ways of studying the brain
- S…. patients with … damage
- E… stimulating the brain
- … scans
- Studying patients with brain damage
- Electrically stimulating the brain
- MRI scans
How does studying patients with brain damage help us understand the brain
-if a s… part has been d… the e… this has on the patient can tell u what the damaged p… does
-if a specific part has been damaged the effect this has on the patient can tell u what the damaged part does
How does electrically stimulating the brain help us understand the brain
-by pushing a tiny ele… into the tissue and giving it a small z.. of …
-by observing what st… the brain does to different parts helps us u… what those parts do
-by pushing a tiny electrode into the tissue and giving it a small zap of electricity
-by observing what stimulating the brain does to different parts helps us understand what those parts do
How do MRI scans help us understand the brain
-a … resonance … (MRI) scanner is a machine that produces very detailed i…. of the brains s….
-helps us find what areas of the brain are a… during certain things
-a magnetic resonance imaging (MRI) scanner is a machine that produces very detailed images of the brains structure
-helps us find what areas of the brain are active during certain things
What negatives can investigating the brain have
-r
-p… d…
-increased problems with b… f…
-risks
-physical damage
-increased problems with brain function
