Parts of the Brain
How do we study the brain?
Accidents Case study analysis of brain injuries IE. Phineas Gage
Phineas Gage Video While you watch think about these questions:What part of the brain deals with emotions What part of the brain deals with judgment
Lesions Lesioning is the removal or destruction of part of the brain.IE. Lobotomy
Essential Questions What are the key functions of the brain?What are the parts for responsible?
Divisions of the Brain
I. The Hindbrain
basic biological functions 3 main parts:Hindbrain basic biological functions 3 main parts: Medulla Cerebellum Pons
Hindbrain parts There are three brain areas associated with the Hindbrain (some parts are associated with Brain Stem): Medulla Cerebellum Pons
Hindbrain parts Medulla: breathing, heart rate and blood pressure…Cerebellum: coordinates voluntary movements and balance (along with the BASIL GANGLIA) Pons: sleep center (among many other things)
Partner Up Get a simile summary for the group of twoYou may pick any part of the hindbrain and make up a simile Have fun with this!
II. The Midbrain
Midbrain hearing and sight pupil dilation and eyeball movementlocated between the hindbrain and the forebrain simple muscle movements with changes in sensory information hearing and sight pupil dilation and eyeball movement
III. The Forebrain
Forebrain thoughts and reason 5 main regions: Thalamus HypothalamusHippocampus Amygdala The Cerebral Cortex
Limbic System includes the thalamus, hypothalamus, hippocampus, and amygdala “emotional brain” helps regulate memory, aggression, fear, hunger, and thirst
Thalamus receives sensory input from all of the senses except smellroutes input to the proper area of the brain for processing “relay center” controls the electrical currents in the brain
Hypothalamus maintenance activities: eating, drinking, fight/flight, and sexual arousal (Four f’s)… Controls the pituitary gland
Hippocampus memory processing
Amygdala emotions, especially those of aggression, rage, and fearIn stressful situations, where teens make some of their decisions
Cerebral Cortex intricate, wrinkled covering of the brain (FISSURES), Covers the brain’s lower level structures ultimate control and information processing center ~ 30 billion nerve cells
Cerebral Cortex In addition to interneurons, it contains GLIAL CELLSguide neural connections, provide nutrients to myelin, and mop up neurotransmitters
Partner Up Get a simile summary for the group of twoYou may pick any part of the forebrain and make up a simile Have fun with this!
Cerebral Cortex split into two halves or Hemispheres: Right HemisphereLeft Hemisphere The two hemispheres of the brain are connected by the CORPUS CALLOSUM
Hemispheres of the Brain
Video Corpus Callosum
Hemispheric Differences“Left-brained” and “right-brained” debunked Brain is divided into two hemispheres but works as a single entity Both sides continually communicate via the corpus callosum
Plasticity The ability of the brain tissue to take on new functionsGreatest in childhood Important if parts of the brain are damaged or destroyed The Story of Jodie
Split Brain ProceduresWhat is the role of the corpus callosum? What happens if we cut the corpus callosum?
LET’S LOOK AT THE LOBES!!!!
The Cerebral Cortex is split into four LOBES:The FRONTAL LOBE The TEMPORAL LOBE The PARIETAL LOBE The OCCIPITAL LOBE
Frontal Lobes just behind the foreheadinvolved in making plans and judgments abstract thought, speaking, muscle movements “Broca’s area”
Temporal Lobes Found near the ears Involved in hearingMemory retrieval
Parietal Lobes behind the frontal lobesgeneral processing, including mathematical reasoning association lobes synesthesia sensation and motor control
Occipital Lobes Located in the back of the headThe primary visual processing area
Freud Tore (his) Pants Off
Motor Cortex At the rear of the frontal lobesControls voluntary movement receives messages from the rest of the brain and then sends messages to muscles contralateral
Somatosensory Cortex Located in the front of the parietal lobesRegisters and processes body senses Soma is Greek for “body”
A Guided Tour of the Brain
THE BRAIN September 18, 2013.
The Central Nervous System
And Brain Organization
Consists of the brain stem pathway for all nerves entering and leaving the brain The Pons-- involved with sleep and alertness; connects brain.
The Brain Module 08. Lower - Level Brain Structures brainstem: oldest, most basic part of brain medulla – controls life-support functions like breathing.
The Brain Module 7 Notes.
The Brain! IIA-3.1 Identify the structure and function of the major regions of the brain. IIA-3.2 Recognize that specific functions are centered in specific.
The Cerebral Cortex is split into four LOBES, with half of each one on the left, and half of each one on the right: The FRONTAL LOBE The PARIETAL LOBE.
The cerebrum or cortex is the largest part of the human brain, associated with higher brain function such as thought and action. The cerebrum controls.
Studying The Brain.
Today is a great day to learn about your BRAIN!!!.
“If the human brain were so simple that we could understand it, we would be so simple that we couldn’t” -Emerson Pugh, The Biological Origin of Human Values.
Neuroscience and Behavior Chapter 2. The Brain! Takes care of all our required tasks (some we do not even give a second thought). The more complex.
