Summary

Pure alexia, a rare reading disorder, can result from damage to the splenium of the callosal corpus or the occipito-temporal cortex. This study proposes a new classification based on lesion location, distinguishing disconnection and cortical alexia.

Area of Science:

Neuroscience
Neurology
Cognitive Science

Background:

Pure alexia, characterized by isolated reading difficulties, is uncommon.
Classical descriptions link it to splenium of the callosal corpus lesions.
Recent findings implicate the occipito-temporal cortex, specifically the visual word form area.

Keywords:

Disconnection Pure alexia Visual word form area

Classification of Neurotransmitters

Classification of Neurotransmitters

Neurotransmitters play a crucial role in the communication between neurons in the autonomic nervous system. Neurons in the autonomic nervous system can be cholinergic or adrenergic depending on the neurotransmitters synthesized. Cholinergic neurons use acetylcholine as their primary neurotransmitter. This includes all the preganglionic fibers of the sympathetic and pre- and postganglionic fibers of the parasympathetic nervous systems. In addition, neurons of the somatic nervous system also use...
