| Marie-Jean-Pierce Flourens helped with what theory of the mind? | Aggregate Field Theory: Function of the mind come from more than 1 specific area. AKA: Emergent properties - The mind is a function of the entire brain |
| Marc Dax is responsible for what discovery? | Broca's Area |
| Paul Broca is responsible for what? | Patient "Tan" research on the lost ability to produce speech due to brain lesions brought on by syphilis. |
| Carl Wernicke is responsible for what? | Left hemisphere and parietal lobes are responsible for speech recognition. |
| Camillo Golgi is responsible for what? | Silver stain to visualize neurons |
| Hebb is responisble for what? | Montreal becoming the birthplace of cognitive neuroscience and Hebbian learning: Neurons that fire together, wire together. |
| Brenda Milner worked on what? | Patient HM - anterograde amnesia after MTL/Hippocampus surgery |
| George Miller identified what rule? | Rule of 7 - 7 (plus or minus two) provides evidence for the capacity of short term memory. Most adults can store between 5 and 9 items in their short-term memory |
| A EEG is? | A electroencephalography test that measure skin conductance. |
| a CT or CAT scan is? | A computed topography or computerized axial tomography - sliced xrays pieced together to create a 3d image. |
| an MRI and fMRI are? | Magnetic resonance functioning - magnetizing blood flow to visualize brain structure and functional brain structure (fMRI) |
| Neurons and _____ are responsible for? | Neurons and glial cells are responsible for neuronal signalling and synaptic transmission. |
| How many glial cells in the brain? | Ratio differs by area by about as many as neurons - 100 billion Cerebral Cortex = 3.7 :1 Cerebellum = 0.23 : 1 |
| Glial cells are responsible for? | Insulation, clean-up, providing structure and helping neuronal migration. They can proliferate even into adulthood. |
| DTI is? | Diffusion Tensor Imaging - Examining white matter tracts by diffusion of water |
| Astrocytes are what? | Glial cells located in the CNS that make up the blood-brain-barrier. Respond to and release Neurotransmitters. |
| Oligodendrocytes are what? | CNS glial cells that make up the myelin sheath. |
| Microglia are what? | Phagocytes that eat garbage and clean up. |
| Ependymal cells are? | Glial cells in the Cerebralspinalfluid (CSF) that have cillia and keep things flowing. |
| Schwann Cells are? | Glial cells in the Peripherial Nervous System that act as the myelin sheath. |
| What are the nodes of ranvier? | Part of the axon that is a gap in the myelin sheath increasing the conduction velocity of action potentials. AKA saltatory conduction |
| Dopamine is produced where? | Basal Ganglia |
| Dorsal/Rorstral/Caudal/Ventral | Superior/Anterior/Posterior/Inferior Up/Front/Back/Bottom |
| The limbic system consists of? | thalamus, hypothalamus, the hippocampus, the amygdala |
| Broddman Area 17 is? | Primary Visual Cortex |
| What is the homunculus? | a topographical map of the brain based on which part affects what. |
| Neuronal proliferation is? | A rapid spreading of neurons starting at the age of 2. 40,000 connections created a second. |
| What are the stages of mental operation? | 1. Encode 2. Compare 3. Decide 4. Respond |
| The Wada test does what? | A test using sodium amytal that goes to 1 half of the brain testing for function in a hemisphere. |
| Ipsilateral/Homotopic/Heterotopic | Same Hemisphere communication Same region on opposite hemisphere communication Different region on opposite hemisphere |
