THE BRAIN AND NERVOUS SYSTEM


What is it called when you can feel emotions?



Psychological Neuroscience 

 Study of the brain and nervous system to better  understand the functioning and possibilities of the brain o Includes the study of the biological foundations of  consciousness, perception, memory, and stress

Nervous System 

 Gathers and process information, procedures, responses  to stimuli and coordinates the workings of different cells o Central Nervous System

 Brain

 Spinal Cord

∙ Nerves collect info, the spinal cord  

responds and sends signal to the brain  

(Below the neck. Above the neck goes  

straight to the brain)

o Peripheral Nervous System

 Somatic


How does a nerve cell communicate with another nerve cell?



 Automatic

∙ Sympathetic: makes you feel emotion  

∙ Parasympathetic: calms you (the sense of  relief after someone scares you, making  

you jump)

Communication 

 Neurons  

o transfer information

 Glia cells (Greek for glue)

o Provide neurons with nutrition, etc.  

Structure of the Neuron 

 Three parts

o Dendrites

 Receive messages from other nerve cells and  sends them to the cell body  

o Cell body

 Contains the nucleus, DNA, neuro chemicals  o Axon

 Transmits message to neurons, muscles,  


Does the umbilical cord contain maternal blood?



glands, etc.

 Myelin sheath (sausage): helps message  

deliver faster and insulates the cell

Neurogenesis 

 Production of new neurons from immature cells  Stem cell research

o Embryonic stem cells If you want to learn more check out Does the total energy of a system remain constant?

 Come from embryo

 From miscarried or aborted fetus

o Non-embryonic stem cells

 From blood in the umbilical cord (also found in  breast milk)

o Reprogramming adult stem cells

Neurotransmitters  

 Chemical substance released by a transmitting  neuron at the synapse  

 Alters the activity of a receiving neuron  

 Some follow a specific path and some are  distributed throughout the brain  

Hormones 

 Chemical substances, secreted by glands, that affect the functioning of glands

 Hormones of interest We also discuss several other topics like How does moment-to-moment affect development?

o Melatonin (sleep)

o Oxytocin (promotes attachment and trust) o Adrenal hormones (stress)

o Sex hormones (estrogen, testosterone, changes  related in sexual arousal  

Neuromodulators 

∙ Chemical substance that modulates the functioning of  neurons and neurotransmitters

o Endorphins (exercise & orgasm)  

Mapping the Brain 

(TMS) transcranial mag stimulations

∙ method of stimulating brain cells  

Electroencephalogram

∙ recording of the electrical activity occurring in the brain  (no precise)

(PETS) Positron Emission Tomography Scan

∙ Method of analyzing the brain changes as they are  occurring

o Measures brains glucose, oxygen and blood flow (MRI) magnetic resonance imaging

∙ Method of studying body and brain tissue that uses  magnetic fields and radio receivers

∙ Functional MRI

o Measure brain activity by changes in blood flow ∙ Structural MRI

o Describes the shape, size and integrity of gray and  white matter structures in the brain We also discuss several other topics like Why is there no regular army?

Tour Through the Brain 

THE BRAIN STEM

Pons

Medulla

Reticular activation systemDon't forget about the age old question of What were the three main parts of the treaty of versailles?

 Cerebellum: sensory information, coordination  movements

 Thalamus: take info from the cerebellum and relays it  to the cerebral cortex If you want to learn more check out What did socrates say about knowledge?

 Hypothalamus: emotions that are vital to survival (4  Fs: feeding, fighting, fleeing and sex.)

 Pituitary gland: produces many hormones that travel  throughout the body, directing certain processes or  stimulating (causing) other glands to produce other  hormones.

 Medulla: arousal, emotions Don't forget about the age old question of What are the different functional groups?

 Hippocampus: Emotional arousal from memory  Cerebrum: larges part of the brain, split in 2 halves’,  connected by a fiber of nerves (corpus callosum) that  allows them to communicated.

o Left: logic (critically thinking)

o Right: responses, “whole picture”, acting.   Cerebral Cortex

∙ Cerebral cortex

o Frontal lobe: conscious thinking, speak production,  making plans, creative thinking.  

 Contains motor cortex.  

 In front of your forehead

o Parietal lobe: processing language and  

mathematics, receive info about taste, touch and  temperature

 top of your head

o Temporal lobe: processes sound, memory, emotion  Above ears

o Occipital lobe: visual context

∙ Prefrontal cortex (Phineas Gage)

∙ Brain Plasticity  

o Change in response to experiences (neurogenesis)

Culture and the Brain

∙ Literacy vs. illiteracy  

o Tech literate people’s brains have stronger neuro  circuits involved with making fast decision and  weaker neuro circuits involved with attention. ∙ Sex

∙ Differences in behavior

o How much of the brain is used for what..  

o White vs. grey
