A new study by SF State Associate Professor of Psychology Ezequiel Morsella suggests that we have less control over our conscious thoughts than previously assumed.
Rats take a fundamentally different approach toward solving a simple visual discrimination task than tree shrews, monkeys, and humans, according to a comparative study of the four mammal species published in eNeuro. The work could have important implications for the translation of research in animal models to humans.
The hippocampus may relay predictions about what we expect to see based on past experience to the visual cortex, suggests a human neuroimaging published in JNeurosci. The study is among the first to examine the interaction between these two aspects of cognition.
Biologists at the Ruhr-Universität Bochum characterized new, unknown photoreceptors from the bioluminescent flashlight fish Anomalops katoptron. The photoreceptors known as opsins allow the fish to detect light with a specific wavelength. As published on the July 11, 2018, in PLOS ONE the scientists found new opsin variants, which are specialized to detect low intensity blue light in the wavelength range of bioluminescent light emitted by the fish. The blue light can be used to influence the fish behavior.
Nerve cells in the brain region planum temporale have more synapses in the left hemisphere than in the right hemisphere -- which is vital for rapid processing of auditory speech, according to the report published by researchers from Ruhr-Universität Bochum and Technische Universität Dresden in the journal Science Advances. There has already been ample evidence of left hemisphere language dominance; however, the underlying processes on the neuroanatomical level had not yet been fully understood.
Structural differences in the cerebellum may be linked to some aspects of autism spectrum disorder, according to a neuroimaging study from Columbia University Irving Medical Center (CUIMC).
The brain's remarkable ability to perceive the outside world relies almost entirely on its capacity to tune out noise generated by the body's own actions, according to a first-of-its-kind study in electric fish led by scientists at Columbia University.
Norah Dunbar's NSF-funded video game trains people to better discern truth from lies -- and how to spot deceptive behavior.
Study finds that six brain regions shared more responsibility than thought for how the brain moves from raw perception to determining the categorical meaning of what's seen.
A new Tel Aviv University study suggests that noradrenaline, a neurotransmitter responsible for arousal in the brain, plays a vital role in early sensory perceptions of the world.
