Bipolar disorder roles of neurotransmitters and signal transduction

Brain imaging and image analysisFunctional image analysisMultivariate image analysis Abstract: However, independent component analysis ICA -based network approach may suffer from such corrections especially if there is any overlap between two sources in the decomposition domain. To address the extent the physiological noise corrections may impact ICA derived intrinsic connectivity brain networks, we measured network features including functional network connectivity FNCpower spectra, and network spatial maps in the resting state and task functional magnetic resonance imaging fMRI data that were acquired in the same visit from a group of healthy volunteers.

Bipolar disorder roles of neurotransmitters and signal transduction

The human nervous system consists of two main parts, the central nervous system CNS and the peripheral nervous system PNS.

The CNS contains the brain and spinal cord. The PNS includes the motor neurons that are responsible for mediating voluntary movement.

The PNS also includes the autonomic nervous system which encompasses the sympathetic nervous system, the parasympathetic nervous system, and the enteric nervous system. The sympathetic and parasympathetic nervous systems are tasked with the regulation of all involuntary activities.

The enteric nervous system is unique in that it represents a semi-independent part of the nervous system whose function is to control processes specific to the gastrointestinal system.

The nervous systems of the body are composed of two primary types of cell: Two important concepts relate to the functioning of the nervous system. These terms are efferent and afferent. Efferent connections in the nervous system refer to those that send signals from the CNS to the effector cells of the body such as muscles and glands.

Efferent nerves are, therefore, also referred to as motor neurons. Afferent connections refer to those that send signals from sense organs to the CNS. For this reason these nerves are commonly referred to as sensory neurons.

Another important cellular structure in nervous systems are the ganglia.

The term ganglion refers to a bundle mass of nerve cell bodies. In the context of the nervous system, ganglia are composed of soma cell bodies and dendritic structures.

The dendritic trees of most ganglia are interconnected to other dendritic trees resulting in the formation of a plexus.

Signal transduction abnormalities in bipolar Bipolar affective disorder (BD), or manic-depressive illness, is a chronic, severe, and debilitating mental disorder characterized by episodes of mania or hypomania. However, recent studies have also implicated critical signal transduction pathways as being integral to the pathophysiology and treatment of BD, in addition to a growing body of data suggesting that impairments of neuroplasticity and cellular resilience may also underlie the pathophysiology of the disorder.

In the human nervous system there are two main groups of ganglia. The dorsal root ganglia, which is also referred to as the spinal ganglia, contains the cell bodies of the sensory nerves.

The autonomic ganglia contain the cell bodies of the nerves of the autonomic nervous system.

Nerves that project from the CNS to autonomic ganglia are referred to as preganglionic nerves or fibers. Conversely, nerves projecting from ganglia to effector organs are referred to as postganglionic nerves or fibers.

Generally the term ganglion relates to the peripheral nervous system. However, the term basal ganglia also basal nuclei is used commonly to describe the neuroanatomical region of the brain that connects the hypothalamus, cerebral cortex, and the brainstem.

Neurons Neurons are the highly specialized cells of all nervous systems e. These cells accomplish this role through specialized membrane-to-membrane junctions called synapses.

Most neuron possess an axon which is a long protrusion from the body soma of the neuron to the synapse. Axons can extend to distant parts of the body and make thousands of synaptic contacts such as is the case with the CNS neurons of the spinal cord.Neurotransmitters and signal transduction processes in bipolar affective disorders: A synopsis Bipolar disorder relates to changes in weight and appetite.

A neuron, also known as a neurone (British spelling) and nerve cell, is an electrically excitable cell that receives, processes, and transmits information through electrical and chemical signals.

These signals between neurons occur via specialized connections called rutadeltambor.coms can connect to each other to form neural rutadeltambor.coms are the primary components of the central nervous.

Introduction: The endocrine system in the body controls hormonal and neurotransmitter production and regulation. In a general sense, a hormone is a cholesterol-based molecule that is released by cells in one part of the body, typically a gland, that affect cells in another part of the body.

The pathology of bipolar disorder (BPD) remains an enigma. The absence of animal models for the disorder has meant that the use of human postmortem brain tissue is still a central approach to understanding its biology.
