Nissl stains - Study guides, Class notes & Summaries

NSC WRITTEN EXAM QUESTIONS. relative refractory period - CORRECT ANSWER period following absolute refractory period, more difficult for the neuron to fire a second AP since membrane is further below threshold (hyperpolarized); more stimulation required Neuron Doctrine (Ramon y Cajal) - CORRECT ANSWER Neurons are discrete, functional units that communicate by contact, not continuity Reticular Theory (Golgi) - CORRECT ANSWER Neurons fuse to form a CONNECTED network/reticulum, making bra...

BEHAVIORAL NEUROSCIENCE: CHAPTER 2 WITH 100% CORRECT ANSWERS ALREADY GRADED A+ 2024 Nissl Stain (what does it stain?) - answer stains the Nissl bodies, also known as the rough endoplasmic reticulum. Nissl Stain (what does it show us?) - answer - distinguishes neurons and glia from one another. - can be used to identify shape and size of the cell soma (body), not the processes (axons and dendrites). (the simple stain shows the organization of the spinal cord)

Behavioral Neuroscience biological psychology Neuroscience scientific study of the brain and nervous system in health and in disease Hippocrates first to suggest that the brain was the source of intelligence Galen introduced "fluid-filled cavity" idea that allow bodies to move, studied with animal dissections and wounded gladiators (later proved wrong) Descartes Mind-body dualism (behavior as it relates to the brain), believed fluidic model Galvani tran...

1. The neuron doctrine states that a) Neurites are fused together to form a continuous network b) Neurites are not continuous and communicate by contact c) Neurons must contain a soma, an axon, and dendrites d) DNA is transcribed to mRNA which is translated into protein b) Neurites are not continuous and communicate by contact 2. Golgi and Ramon y Cajal disagreed over the neuron doctrine; their argument was not resolved until the advent of the electron microscope because: a) Synapse...

USMLE STEP 1 Neurology Exam Review 2023 The notochord induces what to differentiate into what? - Answer-Induces overlying ECTODERM to differentiate into NEUROECTODERM and form NUERAL PLATE Neural plate then gives rise to? - Answer-Neural tube and neural crest cells Notochord becomes what? - Answer-Nucleus pulposus of the intervertebral disks in adults Alar Plate - Answer-Dorsal [Sensory] Same orientation as spinal cord Basal Plate - Answer-Ventral [Motor] Same orientation as the spin...

NEUR 0010 Exam 1 1. What are the physical characteristics of the brain?: Brain is delicate, gelati- nous, collapses under own weight 2. What composes the CNS and PNS?: CNS: brain and spinal cord PNS: nerves outside the brain and spinal cord 3. Is damage permanent if a nerve is severed in the PNS? CNS?: No; yes 4. What was Descartes' flawed theory of neurons?: neurons push fluid through tubes that carry information in the physical brain to body parts (hydraulic system) 5. What did Descartes...

Oxytocin and antidiuretic hormone are two of the hormones secreted by the - ANSWER-Pituitary The primary antibody must be diluted 1:100 for an immunohistochemical procedure. How many micro liters of the primary antibody would be required to prepare a total volume of 2mL? - ANSWER-240 How many grams of NaOH (MW=40) are required to prepare a liter of 1N NaOH? - ANSWER-40 A one normal solution is equivalent to: - ANSWER-1 gram-equivalent weight of solute per 1L of solution (g/L) The num...

How does the perception of faces differ from other objects? - answers-?? Retrieval - answers-The process of getting information out of memory storage. How can retrieval change our memory? - answers-It can reinforce the information and make it stronger. How do errors effect our retrieval? - answers-When we make an error, we are creating the possibility of interference with this incorrect information. It can compete with the right answer. However, if correct feedback is provided, then it ...
