| Question | Answer |
| Golgi Stain | Technique used to visualise silhouettes of individual cells |
| Nissl Stain | Technique used to visualise cell bodies of a selected area Cresyl Violet is the dye used to stain |
| Electron Microscopy | Method of scanning a cell to see very detailed neuronal structure using electron-absorbing substances to project onto a photographic film |
| Neuroanatomical Anterograde Tracing Techniques | Forward tracing paths of axons projecting AWAY from cell bodies that are taken up by cell bodies |
| Neuroanatomical retrograde tracing methods | BACKWARD tracing that investigates pathways of axons INTO the cell bodies |
| Vertebrate nervous system three axes | Anterior - Posterior Dorsal - Ventral Medial - Lateral |
| Brain Dorsal | Up |
| Brain Ventral | Down |
| Brain Posterior | Right |
| Brain Anterior | Left |
| Superior | Top of primate head |
| Inferior | Bottom of primate head |
| Proximal Direction | Closer to CNS |
| Distal Direction | Further away from CNS |
| Grey Matter | Mainly composed of cell bodies and unmyelinated interneurons |
| Spinal Cord White Matter | Largely of myelinated axons |
| Major Divisions of the Brain | 1. Telen (top) 2. Dien 3. Mesen 4. Meten 5. Mylen |
| Telencephalon | Largest division of the human brain and involves the most complex processes Cerebral Cortex (four lobes) Fissures Limbic System Basal Ganglia |
| Cerebral Cortex | Convoluted gray matter with fissures that divide the hemispheres into lobes |
| Gyrus | ridges between fissures and sulci |
| Postcentral Gyrus | sensations of the body |
| Superior Temporal Gyrus | hearing and language |
| Inferior Temporal Cortex | identifies complex visual patterns |
| Medial temporal cortex | certain kinds of memory |
| Neocortex | new cortex, makes up 90% of human cerebral cortex. Consists of 6 layers (I to VI) |
| Pyramidal Cells | large, multipolar neurons with large dendrites and a very long axon |
| Stellate Cells | small, star-shaped interneurons (little or no axon) |
| Hippocampus | (Part of Myelencephalon) plays a part in memory (particularly spatial location) Located in medial temporal lobe |
| Limbic System | Limbic means 'ring' - circles the thalamus regulation of motivated behaviours amygdala cingulate cortex septum |
| Amygdala | Involved in emotion - particularly fear |
| Basal Ganglia | Role in performance of voluntary motor responses Caudate forms a circle with a centre called the putamen Together they are the striatum |
| Diencephalon | Composed of the thalamus and hypothalamus |
| Thalamus | Located on top of brain stem Involved in sensory and motor relay and regulation of consciousness and sleep |
| Thalamic sensory relay nuclei | receive signals from sensory receptors and transmit them to appropriate areas of sensory cortex |
| Hypothalamus | plays a role in regulation of several motivated behaviours(eating sleep and sexual behaviours) regulating the release of hormones from the pituitary gland |
| Mesencephlanon | divided into tectum and tagmentum |
| Metencephlanon | cerebellum and pons |
| Mylencephalon | or Medulla tracts carrying signals between the rest of the brain and the body |
