We present a protocol that allows investigation of the neural correlates of deliberate and automatic emotion regulation, using functional magnetic resonance imaging. This protocol can be used in healthy participants, both young and older, as well as in clinical patients.

Epigenetic Regulation

Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer. In most mammals, females have two X chromosomes (XX) while males have an X and a Y chromosome (XY). The X chromosome contains significantly more genes than the Y chromosome. Therefore, to prevent an excess of X chromosome-linked gene expression in females, one of the two X chromosomes is randomly silenced during early development.

GTPases and their Regulation
0 Views •
2020
Guanine nucleotide-binding proteins (G-proteins), also known as GTPases, are a superfamily of proteins that regulate many cellular processes, such as cell signaling, vesicular transport, and the regulation of cell shape and motility. Mutation or dysfunction of these proteins can lead to disease. There are around 40,000 known G-proteins that can broadly be classified into two groups ‒ small G-proteins consisting of a single domain and large multi-domain G-proteins. Large G-proteins, also known...

Regulated Protein Degradation

2020
It is vital to regulate the activity of enzymatic as well as non-enzymatic proteins inside the cell. This can be achieved either through creating a balance between their rate of synthesis and degradation or regulating the intrinsic activity of the protein. Both these regulation mechanisms play an essential role in the normal functioning of cells. Protein degradation plays two important roles in the cells. It helps to protect cells from misfolded or damaged proteins before they lead to a...

Master Transcription Regulators

2020
Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...
FAQs
Feedback loops compare ongoing internal or external signals with the system’s current state and help adjust neural activity when conditions shift. Sensory information can influence brain networks, while autonomic and endocrine responses modify physiological conditions that feed back to the brain. This continuing exchange supports adjustments in arousal, attention, emotion, and behavior rather than fixed responses.
The autonomic nervous system and endocrine pathways connect neural control with bodily state. Their activity can alter physiological conditions associated with stress, arousal, and adaptation, while those conditions provide signals that influence brain networks in return. Studying these interactions helps neuroscientists examine how regulation extends beyond isolated neural activity to coordinated brain-body control.
Stable internal activity allows neural systems to maintain organized functioning, but excessive stability could limit responses to new demands. Adaptation enables changes in attention, emotion, arousal, and behavior when physiological or environmental conditions change. Brain self-regulation therefore concerns both maintaining functional continuity and adjusting control processes appropriately as circumstances shift.
Sensory signals, physiological state, and environmental demands can all influence regulatory processes. These inputs provide information about changing conditions, allowing brain networks and connected body systems to modify arousal, attention, emotion, or behavior. In neuroscience, examining these influences helps clarify how homeostasis and stress responses interact with cognition and emotion.
Biofeedback and neurofeedback approaches train individuals to influence measurable signals. Biofeedback can focus on physiological signals, whereas neurofeedback focuses on neural signals, as described in the source material. A study or intervention presents information about the selected signal and examines whether participants can alter it over training. These approaches connect measurable regulation with behavioral or clinical research questions.
Research on brain self-regulation and related feedback approaches has potential relevance to mental health, rehabilitation, and personalized interventions. These applications examine whether training or understanding regulatory processes can inform responses involving cognition, emotion, stress, or behavior. The broader scientific value lies in linking measurable physiological or neural signals with individual patterns of regulation and adaptation.
