Neuronal Connectivity as a Determinant of Cell Types and Subtypes

Area of Science:

• Neuroscience
• Computational Neuroscience
• Brain Anatomy

Background:

• Classifying single neurons across the brain is crucial for understanding neural organization.
• Existing classification methods (morphological, transcriptomic, electrophysiological) have limitations in capturing functional diversity.

Conclusions:

• Connectivity is a fundamental feature for defining neuronal identity and brain modularity.
• Neuron connectivity types (c-types) serve as a crucial supplement to transcriptional (t-types), electrophysiological (e-types), and morphological (m-types) classifications.
• This connectivity-based classification advances our understanding of cell types and their roles in brain function.
