Substellar multiplicity in the Hyades cluster [PDF]
, 2013 We present the first high-angular resolution survey for multiple systems among very low-mass stars and brown dwarfs in the Hyades open cluster. Using the Keck\,II adaptive optics system, we observed a complete sample of 16 objects with estimated masses $\

Hippocampal Chandelier Cells Modulate Seizure Susceptibility and Severity
Advanced Science, EarlyView.The axon initial segment (AIS), crucial for action potential initiation, serves as a prime locus for controlling network activity. Chandelier Cells (ChCs), evolved in the mammals, intricately target AISs, acting as gatekeepers for neuronal firing. Diminishing ChC input makes animals more prone to developing seizures, whereas fortifying this connection ...

Imaging of the Stellar Population of IC10 with Laser Guide Star Adaptive Optics and the Hubble Space Telescope [PDF]
, 2007 We present adaptive optics (AO) images of the central starburst region of the dwarf irregular galaxy IC10. The Keck 2 telescope laser guide star was used to achieve near diffraction-limited performance at H and K' (Strehls of 18% and 32%, respectively ...

Advanced Science, EarlyView.Impulsivity is a symptom across multiple psychiatric disorders, yet its neural basis remains elusive. This study shows that the NMDAR antagonist MK‐801 elevates dopamine release and disrupts neuronal selectivity in the nucleus accumbens, leading to impulsive behavior.

Lucky Imaging Adaptive Optics of the brown dwarf binary GJ569Bab
, 2011 The potential of combining Adaptive Optics (AO) and Lucky Imaging (LI) to achieve high precision astrometry and differential photometry in the optical is investigated by conducting observations of the close 0\farcs1 brown dwarf binary GJ569Bab.

Advanced Science, EarlyView.Morphine activates the excitatory cingulate cortex–intermediate rostrocaudal division of zona incerta (Cg‐ZIm) pathway to drive hyperlocomotion in mice. Inhibiting the Cg‐ZIm pathway attenuates both acute and chronic morphine‐induced hyperlocomotion, while its activation mimics morphine's motor effects.

New Extinction and Mass Estimates from Optical Photometry of the Very Low Mass Brown Dwarf Companion CT Chamaeleontis B with the Magellan AO System [PDF]
, 2015 We used the Magellan adaptive optics (MagAO) system and its VisAO CCD camera to image the young low mass brown dwarf companion CT Chamaeleontis B for the first time at visible wavelengths. We detect it at r', i', z', and Ys.

Advanced Science, EarlyView.Genetic and chemical tracking of oligodendrogenesis, combining fiber photometric neuronal activity recording, reveals that distinct oligodendrocyte plasticities are adopted during different phases of motor learning to fine‐tune task‐related neuronal activity, with a preferential involvement of oligodendrogenesis suppression and node lengthening (type 2
