[HTML][HTML] Generic decoding of seen and imagined objects using hierarchical visual features
T Horikawa, Y Kamitani - Nature communications, 2017 - nature.com
Object recognition is a key function in both human and machine vision. While brain decoding
of seen and imagined objects has been achieved, the prediction is limited to training …

Neural decoding of visual imagery during sleep
Visual imagery during sleep has long been a topic of persistent speculation, but its private
nature has hampered objective analysis. Here we present a neural decoding approach in …

[HTML][HTML] Deep image reconstruction from human brain activity
The mental contents of perception and imagery are thought to be encoded in hierarchical
representations in the brain, but previous attempts to visualize perceptual contents have failed …

[HTML][HTML] End-to-end deep image reconstruction from human brain activity
Deep neural networks (DNNs) have recently been applied successfully to brain decoding and
image reconstruction from functional magnetic resonance imaging (fMRI) activity. However…

[HTML][HTML] Hierarchical neural representation of dreamed objects revealed by brain decoding with deep neural network features
T Horikawa, Y Kamitani - Frontiers in computational neuroscience, 2017 - frontiersin.org
Dreaming is generally thought to be generated by spontaneous brain activity during sleep
with patterns common to waking experience. This view is supported by a recent study …

[HTML][HTML] The neural representation of visually evoked emotion is high-dimensional, categorical, and distributed across transmodal brain regions
Central to our subjective lives is the experience of different emotions. Recent behavioral work
mapping emotional responses to 2,185 videos found that people experience upward of 27 …

Reconstructing visual illusory experiences from human brain activity
Visual illusions provide valuable insights into the brain’s interpretation of the world given
sensory inputs. However, the precise manner in which brain activity translates into illusory …

[HTML][HTML] Inter-individual deep image reconstruction via hierarchical neural code conversion
The sensory cortex is characterized by general organizational principles such as topography
and hierarchy. However, measured brain activity given identical input exhibits substantially …

[HTML][HTML] Attention modulates neural representation to render reconstructions according to subjective appearance
T Horikawa, Y Kamitani - Communications Biology, 2022 - nature.com
Stimulus images can be reconstructed from visual cortical activity. However, our perception
of stimuli is shaped by both stimulus-induced and top-down processes, and it is unclear …

[PDF][PDF] Circadian gene circuitry predicts hyperactive behavior in a mood disorder mouse model
Bipolar disorder, also known as manic-depressive illness, causes swings in mood and activity
levels at irregular intervals. Such changes are difficult to predict, and their molecular basis …
