Before providing an operational definition of psychopathy, we first need be clear about what is meant by a personality disorder (PD), based on the current empirical understanding of the nature and structure of PD, because psychopathy is a particular kind of PD. The general criteria for PD in Section II of the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM–5; Cited by: 1.

Exposure to stress during critical periods in development can have severe long-term consequences, increasing overall risk on psychopathology. One of the key stress response systems mediating these long-term effects of stress is the hypothalamic-pituitary-adrenal (HPA) axis; a cascade of central and peripheral events resulting in the release of corticosteroids from Cited by:

We propose that human self-domestication favored the emergence of a less aggressive phenotype in our species, more precisely phenotype prone to replace (reactive) physical aggression with verbal aggression. In turn, the (gradual) transition to verbal aggression and to more sophisticated forms of verbal behavior favored self-domestication, with the two Author: Ljiljana Progovac, Antonio Benítez-Burraco.

Quantitative prediction of aggression in rats by the number of cells within the Amygdala by Dawn Desjardins Download PDF EPUB FB2

Considering the involvement of the amygdala in human aggression (Coccaro et al., ; Van Elst et al.,but also see some exceptions Fanning et al.

The violent offenders behaved more aggressively than controls (aggression frequency vs. 84, p = ) and showed significantly higher brain reactivity to provocations within the amygdala and.

Two major types of aggression, proactive and reactive, are associated with contrasting expression, eliciting factors, neural pathways, development, and function. The distinction is useful for understanding the nature and evolution of human aggression.

Compared with many primates, humans have a high propensity for proactive aggression, a trait shared Cited by: 1. Introduction. Aggressive and violent behavior (henceforth termed as aggression or aggressive behavior) exerts an enormous impact on society at a global gh a precise assessment of the direct and indirect expenditures associated to aggression has been hindered by methodological problems, approximate estimations showed that aggression might cost the Cited by: 1.

Amygdala also plays a very important part in the mechanisms of aggression. Area in ventro-medial amygdala is crucial for the predatory behavior. In an experiment described in the chapter, preoperatively good mousekillers after damage of the ventromedial amygdala completely lost their predatory behavior, that is, interest in the mouse, mouse.

The hypothalamic-pituitary-adrenal (HPA) axis regulates circulating levels of glucocorticoid hormones, and is the major neuroendocrine system in mammals that provides a rapid response and defense against stress (Fig.

Additional findings to be incorporated into the neuroanatomical conceptual framework for drug reward. Recent intracranial self-administration studies in rats have refined our understanding of specific zones within the ventral striatum and VTA that are responsible for the rewarding effects of drugs of abuse (Ikemoto and Wise, ).Although rats learn to self-administer Cited by: After looking up a friend's new number in the phone book, Franklin discovers that the pay phone is being monopolized by someone.

First, the number of cilia was assessed within the rostroventral neural tube (RVNT). Ethanol exposure altered cilia number at the early time points, an effect that returned to baseline by 24 h.

Next, to determine the downstream effects of these cilia abnormalities, key Shh pathway and Shh target genes were examined. In this article the authors address how pathological anxiety may develop from adaptive fear states.

Fear responses (e.g., freezing, startle, heart rate and blood pressure changes, and increased vigilance) are functionally adaptive behavioral and perceptual responses elicited during danger to facilitate appropriate defensive responses that can reduce danger or injury (e.g., escape and Cited by: The orbitofrontal cortex (OFC) is a prefrontal cortex region in the frontal lobes of the brain which is involved in the cognitive process of non-human primates it consists of the association cortex areas Brodmann a 12 and 13; in humans it consists of Brodmann a 11 and The OFC is considered anatomically synonymous with the ventromedial NeuroLex ID: birnlex_ A.

As is evident from the journals name, its scope is broad, ranging from cellular and molecular studies through systems neuroscience, cognition and disease. Results: We have identified over 20 distinct cell-type populations within the mPFC, and over 16 cell-types within the amygdala, including populations of glutamatergic neurons, GABAergic.
