Neuroanatomical Techniques :
Neuroanatomical Techniques Golgi stain – allows for visualization of individual neurons
Nissl stain – selectively stains cell bodies
Electron microscopy – provides information about the details of neuronal structure
Neuroanatomical Tracing Techniques :
Neuroanatomical Tracing Techniques Anterograde (forward)
tracing where axons project away from an area
Retrograde (backward)
tracing where axons are projecting into an area

Directions in the Vertebrate Nervous System (continued)
Directions in the Vertebrate Nervous System (continued) :
Directions in the Vertebrate Nervous System (continued) Anatomical directions ignore the fact that humans walk upright. Therefore, top of the head both “dorsal” (back) and “superior” (top)
Other directions:
Medial – toward the middle
Lateral – toward the side
Proximal – close
Distal – far
Sections of the Brain :
Sections of the Brain Horizontal – a slice parallel to the ground
Frontal (coronal) – slicing bread or salami
Sagittal – a midsagittal section separates the left and right halves
