Keiji Tanaka (田中 慶司) is a Japanese neuroscientist known for his studies on visual object recognition and cognitive control in primates.
Early life and education
- Tanaka earned a B.Sc. in Biophysical Engineering at Osaka University in 1973, and an M.Sc. in the same field in 1975.
- He obtained his Ph.D. from the Faculty of Medicine, University of Tokyo in 1983.
Career and positions
Early in his career, from 1975 to 1989, Tanaka was a researcher at NHK Science & Technical Research Laboratories. In 1989, he joined RIKEN to lead the Laboratory for Neural Information Processing. He later became Head of the Cognitive Brain Mapping Laboratory and has served as Deputy Director of RIKEN BSI.
Research focus
Tanaka’s research focuses on visual object recognition in inferotemporal cortex (IT), investigating how neurons in the ventral visual stream encode object identity, invariances (e.g., viewpoint, scale), and complex feature combinations.[1][2][3][4][5][6][7][8] His work has also contributed to understanding of cognitive control.[9][10][11] More recently, his lab has focused on projection-specific perturbation and causal methods, using double-virus techniques to block specific projections in order to dissect the role of different pathways in visual association and decision-making.[12][13]
His Google Scholar profile reflects work on object representation, neuronal selectivity for complex features, visual cortex coding, and cognitive control.[14]
Honors and influence
Tanaka is recognized among vision neuroscience and primate systems neuroscience communities for his long-term contributions to understanding object encoding, invariance, and the neural basis of recognition. His leadership at RIKEN has supported the growth of cognitive neuroscience in Japan, particularly in bridging anatomical, physiological, and causal circuit methods. His contributions have been recognized by several awards, including[15]
