We have documented the early embryonic development of hypothalamic neurons expressing β-endorphin, α-melanocyte–stimulating hormone, neuropeptide Y, and kisspeptin in rhesus macaques, an animal model that is very similar to humans. Neurons expressing both β-End and αMSH are the first to develop and are initially located in the lateral basal hypothalamus (LBH) as early as day 32–34 of gestation. By day 45 of gestation, these neurons have migrated into the medial basal hypothalamic (MBH) area as their final destination. NPY neurons within the ARH develop later and first appear at day 44 of fetal life, at which time a cluster of neurons is present within the ARH–MBH area. NPY neurons continue to be expressed within the ARH area at all of the later fetal ages analyzed. Similarly, kisspeptin neurons develop later compared with β-End, although only a few cells are present in the ARH by day 44 of gestation, at which time kisspeptin is also expressed in the developing anterior lobe of the pituitary. By day 70 of g...

Each year, SfN's Program Committee invites leading scientists to give lectures on hot topics in neuroscience. Lectures will take place November 15–19 in the San Diego Convention Center, Ballroom 20. Real Time Captioning Services will be provided for all lectures in Ballroom 20. There will be dedicated seating areas and screens that will display the captioned text. Select lectures will be streamed live from the San Diego Convention Center, and an on-demand recording will also be available after the session broadcast for approximately one month after the meeting. Lectures taking place during Neuroscience 2025 are listed below.

The Neuroscience Scholars Program (NSP) welcomes its 2022-2024 cohort on August 1, 2022. Combined with the Program’s past scholars (dating back to 1981), the NSP alumni network now encompasses over 1,200 underrepresented neuroscience researchers at all career stages!

In recent years there has been increased interest in using real-time fMRI (rt-fMRI) feedback to train subjects to intentionally modulate activation of specific brain regions. (Caria et al., 2007; Christoff et al., 2006; deCharms et al., 2004; 2005). The...

At Neuroscience 2019, 135 abstracts (15 per half-day) will be presented in the dynamic poster format. A dynamic poster is different from a regular poster in that it is displayed on a flat, plasma screen connected to a user-provided electronic device (laptop, tablet, etc.) and allows for multimedia content such as videos, audio clips, and animated images or graphs.

To err is human. However, an inappropriate urge does not always result in error. Impulsive errors thus entail both a motor system capture by an urge to act and a failed inhibition of that impulse. Here we show that neuromodulatory electrical stimulation of the supplementary motor complex in healthy humans leaves action urges unchanged but prevents them from turning into overt errors. Subjects performed a choice reaction-time task known to trigger impulsive responses, leading to fast errors that can be revealed by analyzing accuracy as a function of poststimulus time. Yet, such fast errors are only the tip of the iceberg: electromyography (EMG) revealed fast subthreshold muscle activation in the incorrect response hand in an even larger proportion of overtly correct trials, revealing covert response impulses not discernible in overt behavior. Analyzing both overt and covert response tendencies enables to gauge the ability to prevent these incorrect impulses from turning into overt action errors. Hyperpolari...
