Nancy Kanwisher, Doris Tsao, and Winrich Freiwald have been awarded the 2024 Kavli Prize in Neuroscience. The award recognizes their discovery of a specialized system within the brain to recognize faces.

New strategic plan and mission statement guide the funding agency's efforts.

During the journey towards the final destination, neurons change the direction of their migration. Although it has been suggested that external guidance cues are essential for directing neuronal migration to the destination, an intrinsic (or inherent) p...

Despite the vivid experience of homogeneous vision, our visual system is inherently endowed with highly inhomogeneous structures. Although the temporal characteristics of visual responses vary with eccentricity, the connection between this variation, the speed of visual processing, and its underlying neurophysiological mechanisms remains a topic of debate. Here, we performed simultaneous recordings of high-precision gaze positions and EEG activity to investigate how foveal and perifoveal stimulation impact reaction times (RTs) and visual evoked potentials (VEPs). Volunteers discriminated the position and orientation of a U-shaped figure with the aperture facing either upward or downward. Stimuli were presented briefly (50 ms) either in the foveola (0.33◦) or perifovea (6.5◦), to the right or left of the fixation point. Stimulus size in the perifovea condition was adjusted according to the cortical magnification factor (stimulus size: 0.2◦ and 0.75◦ for the foveola and perifovea condition, respectively). Wh...

Neurodevelopmental disorders disproportionately affect males compared with females. The biological mechanisms of this male susceptibility or female protection have not been identified. There is evidence that fetal/neonatal gonadal hormones, which play a pivotal role in many aspects of development, may contribute. Here, we investigate the effects of excess testosterone (T) during a critical period of sex-specific brain organization on social approach and fear learning behaviors in C57BL/6J wild-type mice. Male, but not female, mice treated with T on the day of birth (Postnatal Day 0; PN0) exhibited decreased social approach as juveniles and decreased contextual fear memory as adults, compared with vehicle (veh)-treated controls. These deficits were not driven by anxiety-like behavior or changes in locomotion or body weight. Mice treated with the same dose of T on PN18, which is outside of the critical period of brain masculinization, did not demonstrate impairments compared with the veh group. These finding...
