Neuromodulator release in neurons requires two functionally redundant calcium sensors [PDF]
Neuropeptides and neurotrophic factors secreted from dense core vesicles (DCVs) control many brain functions, but the calcium sensors that trigger their secretion remain unknown. Here, we show that in mouse hippocampal neurons, DCV fusion is strongly and

Nicotinamide adenine dinucleotide (NAD) is a substrate of adenosine diphosphate (ADP)-ribosyl cyclase and is catalyzed to cyclic ADP-ribose (cADPR) by CD38 and/or CD157.

Circadian rhythmogenesis from neuromodulator- and molecular clock-mediated network mixed feedback [PDF]
peer reviewedThe suprachiasmatic nucleus (SCN) is a subset of neurons in charge of timekeeping circadian phenomena. As a network, it is capable of maintaining periodic activity with stable phase-locking patterns in spite of heterogeneous nodes.

Escape steering by cholecystokinin peptidergic signaling
Summary: Escape is an evolutionarily conserved and essential avoidance response. Considered to be innate, most studies on escape responses focused on hard-wired circuits.

Corelease of acetylcholine and GABA from cholinergic forebrain neurons
Neurotransmitter corelease is emerging as a common theme of central neuromodulatory systems. Though corelease of glutamate or GABA with acetylcholine has been reported within the cholinergic system, the full extent is unknown.

Neurotransmitters and Neuromodulators [PDF]
In the central nervous system, besides the neurotransmitters, the occurrence of substances which modify neuronal excitability has been proposed. Since their effect is a matter of modulating neuronal responsiveness, these substances may be called neuromodulators.Examples of neurotransmitters or putative neurotransmitters in the central nervous system ...

Neurochemistry of Visual Attention
Visual attention is the cognitive process that mediates the selection of important information from the environment. This selection is usually controlled by bottom-up and top-down attentional biasing.

Neuromodulation of Attention [PDF]
Attention is critical to high-level cognition and attention deficits are a hallmark of neurologic and neuropsychiatric disorders. Although years of research indicates that distinct neuromodulators influence attentional control, a mechanistic account that traverses levels of analysis (cells, circuits, behavior) is missing.

An Introduction to Predictive Processing Models of Perception and Decision‐Making
Abstract The predictive processing framework includes a broad set of ideas, which might be articulated and developed in a variety of ways, concerning how the brain may leverage predictive models when implementing perception, cognition, decision‐making, and motor control.

Dopamine: The Neuromodulator of Long-Term Synaptic Plasticity, Reward and Movement Control [PDF]
Dopamine (DA) is a key neurotransmitter involved in multiple physiological functions including motor control, modulation of affective and emotional states, reward mechanisms, reinforcement of behavior, and selected higher cognitive functions. Dysfunction
