    Neurons in tree shrew visual cortex project to deeper layers (V and VI). These projections primarily target dendritic spines and shafts, similar to findings in rat visual cortex, offering insights into cortical circuitry.

    Area of Science:

    • Neuroscience
    • Visual Cortex Research
    • Cortical Circuitry

    Background:

    • Understanding intracortical projections is crucial for deciphering visual information processing.
    • Previous studies in rodents provide a basis for comparison.

    Purpose of the Study:

    • To investigate the intracortical projections of neurons in layers II and upper III of the tree shrew visual cortex.
    • To characterize the targets of these projections using ultrastructural analysis.

    Main Methods:

    • Terminal lesions were induced in the supragranular layers of area 17 in tree shrews.
    • Ultrastructural techniques were employed to examine terminal degeneration.
    • The distribution of degenerating terminals on neuronal profiles was quantified.

    Main Results:

    • The majority of degenerating terminals were observed in layers V and VI.
    • These terminals were presynaptic to dendritic spines (80.5%) and dendrite shafts (19%).
    • Degenerating axons formed vertical bundles traversing multiple cortical layers.

    Conclusions:

    • Intracortical projections from superficial layers of the tree shrew visual cortex target deeper cortical layers.
    • The synaptic targets are predominantly dendritic spines and shafts.
    • These findings align with observations in the rat visual cortex, suggesting conserved circuitry principles.
