Mild traumatic brain injury (mTBI) is the most common type of traumatic brain injury globally. Although its consequences may be short term, mTBI often leads to long-term neuropsychiatric and neurological impairments and has been estimated to increase the probability of later life dementia up to six-fold. It is presently not clear what neuropathological changes underlie […]

In 1973 John Heuser and Tom Reese demonstrated that neurotransmitter was released from neurons via the fusion of neurotransmitter-filled vesicles with the cell membrane.  But at the same time, these experiments launched a controversy that is unresolved today – do vesicles collapse into the membrane and are then recycled slowly on the order of 20 […]

Dopamine is a neuromodulator that codes information on various time scales. I will discuss recent progress on the identification of fast release mechanisms for dopamine in the mouse striatum. I will present data on triggering mechanisms of dopamine release and evaluate its roles in striatal regulation. In the long-term, our work will allow for a better understanding of the mechanisms and […]

Mammals use a sophisticated, multi-regional memory system to guide behavior. A major goal of neuroscience is to understand the mechanisms—ranging from molecular to cellular to systems—that make this possible. Spruston will describe recent results from his lab using mouse behavior, patch-clamp recording, imaging, and RNA-seq, which collectively seek to elucidate how a diverse and complex […]

The Heller Lab research program is focused on discovering molecular mechanisms by which epigenetic reprogramming contributes to neuropsychiatric disease. To this end, Dr. Heller pioneered the use of targeted epigenetic editing in brain, to elucidate the precise causal role of histone posttranslational modifications on gene expression and alternative splicing in specific neuronal subpopulations. Dr. Heller […]

Metabolic MRI allows observing energy metabolism, neurotransmission, second messaging, endocrine signaling, antioxidants, protein metabolism and dynamic membrane processes in the human brain. Related quantitative metabolic imaging biomarkers are beneficial for differential diagnostics, monitoring of treatment response and patient stratification in various neurological and psychiatric disorders and yield complementary information to structural and functional imaging. To […]

Microglia are the primary immune cell of the brain, but have roles outside of immunity as well as being implicated in the pathogenesis of many CNS disorders. Here I will show how we can use CSF1R inhibitors to control the microglial population in vivo, and elucidate their functions in both the homeostatic and disease brains. […]

Molecular imaging (primarily PET) has become an indispensable tool in early phase drug development, […]

For decades, neuroscience has focused almost exclusively on stereotyped, reductionist, and over-trained behaviors due to their ease of study. In contrast, naturalistic behavior provides a rich diversity of movements, but this feature also largely precludes it from quantification and use. Recent advances in computer vision have enabled automatic tracking of the position of body parts - but position […]

Here we will discuss cell communications in the meninges that regulate patrolling T cells and how the […]

The current model has […]
