The series of molecular signals generated as a consequence of a G protein-coupled acetylcholine receptor binding to its physiological ligand, where the pathway proceeds with inhibition of adenylyl cyclase and a subsequent decrease in the concentration of cyclic AMP (cAMP).

The series of molecular signals generated as a consequence of a G protein-coupled receptor binding to its physiological ligand, where the pathway proceeds with activation of phospholipase C (PLC) and a subsequent increase in the concentration of inositol trisphosphate (IP3) and diacylglycerol (DAG).

The series of events required for an organism to receive a painful stimulus, convert it to a molecular signal, and recognize and characterize the signal. Pain is medically defined as the physical sensation of discomfort or distress caused by injury or illness, so can hence be described as a harmful stimulus which signals current (or impending) tissue damage. Pain may come from extremes of temperature, mechanical damage, electricity or from noxious chemical substances. This is a neurological process.

The series of molecular signals generated as a consequence of an opioid receptor binding to one of its physiological ligands.

Any process which stops, prevents, or reduces the frequency, rate or extent of cAMP-mediated signaling, a series of molecular signals in which a cell uses cyclic AMP to convert an extracellular signal into a response.

Any process that stops, prevents, or reduces the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of nitric oxide.

Any process that activates or increases the frequency, rate or extent of neurogenesis, the generation of cells within the nervous system.

Any process that decreases the concentration of calcium ions in the cytosol.

Any process that stops, prevents, or reduces the frequency, rate or extent of the controlled release of a Wnt protein from a cell.

Any process that activates or increases the frequency, rate or extent of signal transduction mediated by the ERK1 and ERK2 cascade.

Any process that modulates the frequency, rate or extent of N-methyl-D-aspartate selective glutamate receptor activity.

A vacuole to which materials ingested by endocytosis are delivered.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

The long process of a neuron that conducts nerve impulses, usually away from the cell body to the terminals and varicosities, which are sites of storage and release of neurotransmitter.

A neuron projection that has a short, tapering, morphology. Dendrites receive and integrate signals from other neurons or from sensory stimuli, and conduct nerve impulses towards the axon or the cell body. In most neurons, the impulse is conveyed from dendrites to axon via the cell body, but in some types of unipolar neuron, the impulse does not travel via the cell body.
