Please spread the word: We’re recruiting a postdoc! 📣 We study how shifting brain & attentional states shape memory and how people experience their worlds. fMRI/iEEG + a fun, supportive lab community + space to pursue your own ideas. 📅 Apply by Aug 15 tinyurl.com/fx5k7teb

New paper with @paulm-k.bsky.social and Mark Stokes on how we switch internal attention between working memory contents. Beta-band oscillations tracked the magnitude and success of these switches. www.jneurosci.org/content/46/1... #neuroskyence

Human Beta Oscillations Reflect Magnitude and Fidelity of Priority Shifts in Working Memory

Flexible prioritization in working memory (WM) is supported by neural oscillations in frontal and sensory brain areas, but the roles of different oscillations remain poorly understood. Recordings in h...

Many claim memory biases toward percepts reflect corruption in sensory signals. We challenge this view by showing that ppl adapt their integration rationally w/ experience. w/ @timbrady.bsky.social Humans adaptively integrate memory and perception based on stimulus history | osf.io/preprints/ps...

🧠 The MackLab (@drmack.bsky.social) will be presenting at #CNS2026! Stop by our posters to chat about learning, insight, and hippocampus!

#JNeurosci: Results from Hall-McMaster, @nicoschuck.bsky.social, @gershbrain.bsky.social et al suggest the entorhinal cortex might highlight aspects of past experiences that can be generalized, allowing us to make effective decisions in new environments https://doi.org/10.1523/JNEUROSCI.1492-25.2025

🎉 New preprint 🎉 with Olya Bulatova, @drmack.bsky.social & @keisukefukuda.bsky.social! We decode shapes in working memory from EEG and show that representations are task-dependent, flexibly integrating information about category and task during the memory delay

How do hippocampal pathways contribute to learning regularities and exceptions? To answer this, Melisa Gumus & @drmack.bsky.social use diffusion imaging to identify the endpoints of different hippocampal pathways, and then analyze functional activity within those "footprints". Super innovative!
