Azcorra M, Gaertner Z, Davidson C, He Q, Kim H, Nagappan S, et al.
Nat Neurosci
. 2023 Aug;
26(10):1762-1774.
PMID: 37537242
Dopamine neurons are characterized by their response to unexpected rewards, but they also fire during movement and aversive stimuli. Dopamine neuron diversity has been observed based on molecular expression profiles;...

PMID: 34913870
Understanding how distinct neuron types in a neural circuit process and propagate information is essential for understanding what the circuit does and how it does it. The olfactory (piriform, PCx)...

Cell Rep
. 2021 Apr;
35(3):109001.
PMID: 33882304
It is well established that seizures beget seizures, yet the cellular processes that underlie progressive epileptogenesis remain unclear. Here, we use optogenetics to briefly activate targeted populations of mouse piriform...

PMID: 32662420
Pattern completion, or the ability to retrieve stable neural activity patterns from noisy or partial cues, is a fundamental feature of memory. Theoretical studies indicate that recurrently connected auto-associative or...

Cereb Cortex
. 2018 Sep;
29(8):3415-3426.
PMID: 30192931
Recent evidence shows that seizures propagate primarily through supragranular cortical layers. To selectively modify these circuits, we developed a new technique using tightly focused, femtosecond infrared laser pulses to make...

PMID: 29316416
A new study reports unsupervised, experience-dependent reorganization, but not stabilization, of neural odor representations in the zebrafish olfactory system.
