Overview command and control center
Overview: Command and Control Center

Brain is more complex than supercomputer

New technologies allow us to map brain activity in action


Concept 49 1 nervous systems consist of circuits of neurons and supporting cells
Concept 49.1: Nervous systems consist of circuits of neurons and supporting cells

Nervous systems relay information within the body

Nervous system evolved billions of years ago when ability to detect and react to environment in prokaryotes aided enhanced survival


Concept 49 2 the vertebrate brain is regionally specialized
Concept 49.2: The vertebrate brain is regionally specialized and supporting cells

During embryonic development too many neurons are present and they undergo apoptosis to form specialized regions and the brain goes from smooth to convoluted


Concept 49 2 the vertebrate brain is regionally specialized1
Concept 49.2: The vertebrate brain is regionally specialized and supporting cells

Gray matter is layered over white matter. White matter is myelinated. Gray matter is not


Concept 49 2 the vertebrate brain is regionally specialized2
Concept 49.2: The vertebrate brain is regionally specialized and supporting cells

Each region regulates specific functions although there is overlap among different regions and information gets integrated.


Concept 49 3 the cerebral cortex controls voluntary movement and cognitive functions
Concept 49.3: The cerebral cortex controls voluntary movement and cognitive functions

The cerebral cortex is the highly convoluted outer layer of the brain that is involved in higher thinking such as creativity, memory, and learning


Concept 49 4 changes in synaptic connections underlie memory and learning
Concept 49.4: Changes in synaptic connections underlie memory and learning

Changes in synapses such as gain or loss or change in signal strength cause changes in memory and learning.

Short term memory is formed in hippocampus

Long term memory is formed in cerebrum


Concept 49 5 nervous system disorders can be explained in molecular terms
Concept 49.5: Nervous system disorders can be explained in molecular terms

Disorders such as Alzheimer’s, Schizophrenia, and Bipolar disorders can be explained on the molecular level and usually have to do with faulty neurotransmitters

Stem cells present in adult brain offer treatment options through induction of differentiation of transplantation of cultured stem cells
