Semantic cognition permits us to bring meaning to our verbal and nonverbal experiences and to generate context- and time-appropriate behavior [1,2]. It is core to language and nonverbal skilled behaviors and, when impaired after brain damage, it generates significant disability [3]. A fundamental neuroscience . . . → Read More: Category-Specific versus Category-General Semantic Impairment Induced by Transcranial Magnetic Stimulation

Animals negotiating complex natural terrain must consider cues around them and alter movement parameters accordingly [1, 2,1, 2]. In the arthropod brain, the central complex (CC) receives bilateral sensory relays and sits immediately upstream of premotor areas, suggesting that it may be involved in the . . . → Read More: Neural Activity in the Central Complex of the Insect Brain Is Linked to Locomotor Changes

One of the fundamental goals of neuroscience is to understand how perception arises from the activity of neurons in the brain [1]. Stereopsis is a type of three-dimensional (3D) perception that relies on two slightly different projections of the world onto the retinas of the two eyes, i.e., . . . → Read More: Contribution of Inferior Temporal and Posterior Parietal Activity to Three-Dimensional Shape Perception

Perceptual learning has been documented in adult humans over a wide range of tasks. Although the often-observed specificity of learning is generally interpreted as evidence for training-induced plasticity in early cortical areas, physiological evidence for training-induced changes in . . . → Read More: Perceptual Learning Improves Contrast Sensitivity of V1 Neurons in Cats
