What are serotonin neurons trying to tell the brain? Our work on the question has been so much fun (@JCBeique , @JermiahYCohen, @grossmancooper ). Check out @efharkin_ 's exciting paper biorxiv.org/content/10.1101/… nature.com/articles/s41586-0…

Serotonin predictively encodes value

The in vivo responses of dorsal raphe nucleus (DRN) serotonin neurons to emotionally-salient stimuli are a puzzle. Existing theories centred on reward, surprise, or uncertainty individually account...

Stability of cross-sensory input to primary somatosensory cortex across experience

Kato and Bruno show that, despite responding to sounds, rodent primary somatosensory cortex (S1) encodes neither the identity of pure auditory stimuli nor simultaneous auditory-tactile stimulus...

Perception is multimodal—we recognize objects in the world by combining touch, sight, sound, smell, and taste. Primary sensory cortical areas (S1, V1, A1, …) respond to other modalities. Could a primary area bind together different modalities, like an association cortex? 🧵

We grieve the passing of Dr. Yves Frégnac. Yves has shaped the study of cortical processing and plasticity. He heralded interdisciplinarity and was one of the founding fathers of our institute. Our thoughts go to his family and to his friends in the community and beyond. xitter.cf/NeuroPSI_saclay/status…

How 1% FSIs in the striatum may shape the striatal function: 1. they control across-trial variability 2. they give rise to a correlation attractor. Functional consequences of fast-spiking interneurons in striatum biorxiv.org/content/10.1101/…

Functional consequences of fast-spiking interneurons in striatum

The striatum features a distinct network characterized by a high degree of shared feedforward inhibition (FFI) from a mere 1% of fast-spiking interneurons (FSI). We investigate the potential roles of...

Die Wissenschaft braucht Rechtssicherheit und ein Gesetz, das Tierwohl in den Mittelpunkt stellt, aber biomedizinischen Fortschritt nicht verhindert. Dieser Gesetzentwurf treibt Deutschland‘s nächste Generation an WissenschaftlerInnen aus dem Lande und aus der Wissenschaft.
Stefan Treue@StefanTreue25 Apr 2024
Es gibt keine "Kampagne" der Wissenschaft "gegen das Gesetz"! Stattdessen stellt der Artikel klar, dass eine Strafverschärfung gegen die man sich trotz bester Rechtskenntniss nicht schützen kann keine Lösung ist. Gebraucht wird Rechtssicherheit, statt Strafandrohung.

Congrats to amazing first authors @mkorympidou Sarah Strauss 🎉 We study how a diverse class of inhibitory neurons contribute to color processing in the retina 📢Key finding: They balance biased color signals biorxiv.org/content/10.1101/… W/ @AnnaIntegrated @teulerlab @CellTypist

GABAergic amacrine cells balance biased chromatic information in the mouse retina

The retina extracts chromatic information present in an animal’s environment. In the mouse, the feed-forward, excitatory pathway through the retina is dominated by a chromatic gradient, with green...

Disinhibition enables vocal repertoire expansion after a critical period

The efficiency of motor skill acquisition is age-dependent, making it increasingly challenging to learn complex maneuvers later in life [1][1]–[6][2]. Zebra finches, for instance, acquire a complex...
