DOI: 10.1007/s00204-017-2047-1
Abstract: Bisphenol A (BPA), a common environmental xenoestrogen, has been implicated in physiological and behavioral impairment, but the neuronal basis remains elusive. Although various synaptic mechanisms have been shown to mediate BPA-induced brain deficits, there are… read more here.

DOI: 10.1016/j.clineuro.2020.105746
Abstract: OBJECTIVES When using MEG for pre-surgical mapping it is critically important that reliable estimates of functional locations, such as the primary visual cortex (V1) can be provided. Several different models of MEG systems exist, each… read more here.

DOI: 10.1016/j.cub.2020.10.046
Abstract: The development of the visual system is known to be shaped by early-life experience. To identify response properties that contribute to enhanced natural scene representation, we performed calcium imaging of excitatory neurons in the primary… read more here.

DOI: 10.1016/j.isci.2020.101882
Abstract: Summary All rodents investigated so far possess orientation-selective neurons in the primary visual cortex (V1) but – in contrast to carnivores and primates – no evidence of periodic maps with pinwheel-like structures. Theoretical studies debating… read more here.

DOI: 10.1038/s41467-019-10498-1
Abstract: Spatiotemporally synchronised neuronal activity is central to sensation, motion and cognition. Brain circuits consist of dynamically interconnected neuronal cell-types, thus elucidating how neuron types synergise within the network is key to understand the neuronal orchestra.… read more here.

DOI: 10.1038/s41467-020-15386-7
Abstract: Crowding is a profound loss of discriminability of visual features, when a target stimulus is surrounded by distractors. Numerous studies of human perception have characterized how crowding depends on the properties of a visual display.… read more here.

DOI: 10.1038/s41598-019-56608-3
Abstract: Attention greatly influences sensory neural processing by enhancing firing rates of neurons that represent the attended stimuli and by modulating their tuning properties. The cholinergic system is believed to partly mediate the attention contingent improvement… read more here.

DOI: 10.1073/pnas.2108882119
Abstract: Significance Rapid detection and processing of stimulus novelty are key elements of adaptive behavior. Predictive coding theories postulate that novel stimuli should be encoded differently from familiar stimuli. Here, we show that the majority of… read more here.

Abstract: The mind affects the body via central nervous system (CNS) control of the autonomic nervous system (ANS). In humans, one striking illustration of the "mind-body" connection is that illusions, subjectively perceived as bright, drive pupil… read more here.

DOI: 10.1097/wnr.0000000000001849
Abstract: Previous neuroimaging studies have demonstrated that comitant exotropia (CE) patients exhibit dysfunction in various visual cortical areas. However, whether the CE patients showed abnormal dynamic functional connectivity (dFC) in primary visual cortex (V1) changes remains… read more here.
