Experimental Neuroanatomical Research
Spinal cord and brainstem primary afferent connections, as well as ascending spinal pathways, in particular spinocerebellar pathways, have been studied by experimental approaches.
Studies of retrograde neuronal degeneration resulted in the finding of ”transganglionic degeneration”. This is characterized by changes of central processes of primary sensory neurons following damage of their peripheral branches.
Refined methods have been developed for tracing connections.
More recently, focus has been on history of neuroscience.
