Even though intimacy has been broadly defined in terms of romantic love and sexual desire , the neuroanatomy of intimacy needs further explanation in order to fully understand their neurological functions in different components within intimate relationships, which are romantic love, lust , attachment , and rejection in love. Also, known functions of the neuroanatomy involved can be applied to observations seen in people who are experiencing any of the stages in intimacy. Research analysis of these systems provide insight on the biological basis of intimacy , but the neurological aspect must be considered as well in areas that require special attention to mitigate issues in intimacy, such as violence against a beloved partner or problems with social bonding. Pair bonding , or intense social attachment, normally initiates partner preference in sexual situations and monogamy in many mammalian species. Monogamous species generally exhibit an exclusive responsibility to each other as well as co-parenting to their offspring. In this pathway, dopamine is released from the ventral tegmental area VTA to the nucleus accumbens and prefrontal cortex , which then signals the ventral pallidum to complete reward processing in the pathway. Two important neuropeptides that mediated pair bond formation were oxytocin and arginine vasopressin AVP.

Despite considerable effort, the neural correlates of altered threat-related processing in panic disorder PD remain inconclusive. Mental imagery of disorder-specific situations proved to be a powerful tool to investigate dysfunctional threat processing in anxiety disorders.

Visual-spatial working memory measures are widely used in clinical and experimental settings. Furthermore, it has been argued that the male advantage in spatial abilities can be explained by a sex difference in visual-spatial working memory. Therefore, sex differences in visual-spatial working memory have important implication for research, theory, and practice, but they have yet to be quantified. The present meta-analysis quantified the magnitude of sex differences in visual-spatial working memory and examined variables that might moderate them. Multilevel meta-analysis was used on the overall data set to account for non-independent effect sizes. The data also were analyzed in separate task subgroups by means of multilevel and mixed-effects models.

Media portraying violence is part of daily exposures. The extent to which violent media exposure impacts brain and behavior has been debated. Yet there is not enough experimental data to inform this debate. The source of the variability, we further hypothesize, is reflected in autonomic response and brain functioning that differentiate those with aggression tendencies from others. To test this hypothesis we pre-selected a group of aggressive individuals and non-aggressive controls from the normal healthy population; we documented brain, blood-pressure, and behavioral responses during resting baseline and while the groups were watching media violence and emotional media that did not portray violence.

Distinct neural mechanisms underlie the success, precision, and vividness of episodic memory

A network of brain regions have been linked with episodic memory retrieval, but limited progress has been made in identifying the contributions of distinct parts of the network. Here, we utilized continuous measures of retrieval to dissociate three components of episodic memory: retrieval success, precision, and vividness. In the fMRI scanner, participants encoded objects that varied continuously on three features: color, orientation, and location.

 Ну конечно, - сказала она, все еще не в силах поверить в произошедшее.  - Он хотел, чтобы вы восстановили его доброе имя. - Нет, - хмуро сказал Стратмор.  - Танкадо потребовал ТРАНСТЕКСТ. - ТРАНСТЕКСТ.

У нас только настоящие андалузские красавицы. - Рыжие волосы, - повторил Беккер, понимая, как глупо выглядит. - Простите, у нас нет ни одной рыжеволосой, но если вы… - Ее зовут Капля Росы, - сказал Беккер, отлично сознавая, что это звучит совсем уж абсурдно. Это странное имя, по-видимому, не вызвало у женщины каких-либо ассоциаций.

Я позвоню и все объясню. - Из самолета? - повторила.  - Что происходит. С какой стати университетский профессор… Это не университетские дела.
