Matsui T, Hashimoto T, Murakami T, Uemura M, Kikuta K, Kato T, et al.
Nat Commun
. 2024 Dec;
15(1):10055.
PMID: 39632809
How biological neural networks reliably process information in the presence of spontaneous activity remains controversial. In mouse primary visual cortex (V1), stimulus-evoked and spontaneous activity show orthogonal (dissimilar) patterns, which...

Nomura S, Terada S, Ebina T, Uemura M, Masamizu Y, Ohki K, et al.
Nat Commun
. 2024 Sep;
15(1):7633.
PMID: 39256380
Genetically encoded fluorescent sensors continue to be developed and improved. If they could be expressed across multiple cortical areas in non-human primates, it would be possible to measure a variety...

Nat Commun
. 2024 Aug;
15(1):7127.
PMID: 39164245
Sensorimotor learning requires reorganization of neuronal activity in the premotor cortex (PM) and primary motor cortex (M1). To reveal PM- and M1-specific reorganization in a primate, we conducted calcium imaging...

. 2023 Sep;
167:875-889.
PMID: 37722983
Recent studies in deep neural networks have shown that injecting random noise in the input layer of the networks contributes towards ℓ-norm-bounded adversarial perturbations. However, to defend against unrestricted adversarial...

Biochem Biophys Res Commun
. 2023 Aug;
678:102-108.
PMID: 37625269
The extent to which resting-state hemodynamics reflects the underlying neural activity is still under debate. Especially in the delta frequency band (0.5-4 Hz), it is unclear whether the hemodynamics can...

Aging Cell
. 2023 Jul;
22(9):e13925.
PMID: 37476844
Neurons decline in their functionality over time, and age-related neuronal alterations are associated with phenotypes of neurodegenerative diseases. In nonneural tissues, an infolded nuclear shape has been proposed as a...

Murakami T, Ohki K
Front Neural Circuits
. 2023 May;
17:1155195.
PMID: 37139079
External sensory inputs propagate from lower-order to higher-order brain areas, and the hierarchical neural network supporting this information flow is a fundamental structure of the mammalian brain. In the visual...

PMID: 36001081
The developing neocortex exhibits spontaneous network activity with various synchrony levels, which has been implicated in the formation of cortical circuits. We previously reported that the development of callosal axon...

Nature
. 2022 Aug;
608(7923):578-585.
PMID: 35922512
Hierarchical and parallel networks are fundamental structures of the mammalian brain. During development, lower- and higher-order thalamic nuclei and many cortical areas in the visual system form interareal connections and...

PMID: 35296036
Neurons in the mouse primary visual cortex (V1) exhibit characteristic response selectivity to visual stimuli, such as orientation, direction and spatial frequency selectivity. Since V1 receives thalamic visual inputs from...
