Which
stain is used todistinguish the grey and white matter in the brain? And what does isstain ?Nissl stain
Stains neuron cell bodies/soma -
Why is it difficult to classify neurons in the NS ?You need to define a parameter space in order to do the classification. The definition of the parameters space is subjective.
-
How does an axon make contactThe
boutons/synaptic terminals of axons make contact the dendrites of postynaptic neurons. -
............. is formed by neuronal structures that are distributed across different regions of the brain but work together to perform a given function.
System -
Are spines dendritic or axons extensions?Dendritic
-
In a typical neuron the largest density of synapses are made onto the ..........Axon/stoma or dendrite?Dendrite
-
Who originally visualised and described the Axo-dendritic projections ?Ramon y Cajal
-
How do Inhibitory neurons work?They secrete neurotransmitters that cause membrane hyperpolarization in postsynaptic neurons.
-
What does Dale's law (1934) state?A neuron is either excitatory or inhibitory in its influence on other neurons
A neuron secretes a single (traditional) neurotransmitter at its synapses -
Name a few modern techniques allow detailed anatomical characterisation of neurons.For example,
Molecular labeling in whole brain provide biochemical insight to neuronal diversity.
