MIRO1 mutation leads to metabolic maladaptation resulting in Parkinson's disease-associated dopaminergic neuron loss

6 months 2 weeks ago
MIRO1 is a mitochondrial outer membrane protein important for mitochondrial distribution, dynamics and bioenergetics. Over the last decade, evidence has pointed to a link between MIRO1 and Parkinson's disease (PD) pathogenesis. Moreover, a heterozygous MIRO1 mutation (p.R272Q) was identified in a PD patient, from which an iPSC-derived midbrain organoid model was derived, showing MIRO1 mutant-dependent selective loss of dopaminergic neurons. Herein, we use patient-specific iPSC-derived midbrain...

Mnemonic brain state engagement is diminished in healthy aging

6 months 2 weeks ago
Healthy older adults typically show impaired episodic memory - memory for when and where an event occurred. This selective episodic memory deficit may arise from differential engagement in the retrieval state, a brain state in which attention is focused internally in an attempt to access prior knowledge, and the encoding state, a brain state which supports the formation of new memories and that trades off with the retrieval state. We hypothesize that older adults are biased toward a retrieval...
