Minimal circuit motifs for second-order conditioning in the insect mushroom body

open access: yesFrontiers in Physiology
In well-established first-order conditioning experiments, the concurrence of a sensory cue with reinforcement forms an association, allowing the cue to predict future reinforcement.

Prefrontal cortex iron content in neurodegeneration and healthy subjects: A systematic review

open access: yesIbrain, EarlyView.
This systematic review summarizes magnetic resonance imaging (MRI)‐based assessments of prefrontal cortex (PFC) iron accumulation in healthy individuals and patients with neurodegenerative diseases. The review includes 12 studies using techniques such as susceptibility‐weighted imaging (SWI), quantitative susceptibility mapping (QSM), and R2* mapping ...

TGF-β promotes survival on mesencephalic dopaminergic neurons in cooperation with Shh and FGF-8

open access: yesNeurobiology of Disease, 2004
Impaired neuronal survival is a key event in the development of degenerative diseases, such as Parkinson's disease (PD). Here we show that transforming growth factor beta (TGF-β) acts directly on rat E14 midbrain dopaminergic neurons in vitro, its ...

Crosstalk of parkin and Ret in dopaminergic neurons

open access: yesOncotarget, 2015
Recent genetic and functional studies have revealed striking similarities in the protein networks and molecular mechanisms altered in cancer and Parkinson's disease, as illustrated here for the converging signaling pathways of parkin and Ret [1]. These similarities may guide our thinking about potential therapies for both diseases.

Engineered Living Energy Materials

open access: yesInterdisciplinary Materials, EarlyView.
Engineered living energy materials (ELEMs) are nascent research frontier for enabling sustainable energy conversion and storage. These materials exhibit unique characteristics such as self‐regeneration, biodegradability, environmental response, and evolutionary adaptability. This paper overviews different energy conversion bio‐modules, summarizes their

Independent Contributions of Discrete Dopaminergic Circuits to Cellular Plasticity, Memory Strength, and Valence in Drosophila

open access: yesCell Reports, 2019
Summary: Dopaminergic neurons play a key role in encoding associative memories, but little is known about how these circuits modulate memory strength. Here we report that different sets of dopaminergic neurons projecting to the Drosophila mushroom body ...
