Abstract

Abstract

En 中文
The ventral temporal cortex (VTC) is a brain area involved in identifying and categorizing visual stimuli. Wadia et al. performed single-neuron recording in the VTC of patients with epilepsy while the subjects were presented with real visual stimuli or were asked to imagine them. Deep network analysis showed that visually responsive neurons were tuned on specific axes. While imagining the objects, around 40% of the visually responsive VTC neurons were also robustly activated. Thus, mental imagery reactivates the same sensory codes used during visual stimuli, suggesting the existence of a generative model capable of synthesizing detailed sensory contents from an abstract, semantic representation. —Mattia Maroso
