Neurobiology of Learning and Valuation
<p>An animal's ability to make adaptive choices is key to its fitness. Thus, the process of determining options, making a decision, evaluating outcomes, and learning from those outcomes to adjust future behavior is a central function of our nervous system. Determining the neural mechanisms of these …

Neurobiology of incremental speech comprehension
Understanding spoken language requires the rapid transition from perceptual processing of the auditory input through a variety of cognitive processes involved in constructing the mental representation of the message that the speaker is intending to convey. Listeners carry out these complex …

Smoking Status, Cognition, and Neurobiology in Schizophrenia
Cognitive impairments are considered a core feature of schizophrenia. Nicotine has been suggested to have an effect on cognition in individuals with schizophrenia and in the general population. Since smoking status is seldom controlled for in cognitive research studies understanding the …

The Neurobiology of Reward Processing in Adolescence
Adolescence represents a time in development when the reward system undergoes substantial changes. Several studies suggest differences in reward processing amongst adolescents compared to adults and children. Abnormalities in reward processing also underlie many psychiatric disorders, such as …

Exploiting entomopathogenic nematode neurobiology to improve bioinsecticide formulations
Entomopathogenic nematodes (EPNs) are soil dwelling organisms that target and kill insects. They have sophisticated chemosensory apparatus, with which they perceive host associated cues to locate them. Once a suitable host is located, they employ a diverse range of host finding behaviours to …

Towards a cognitive neurobiology of brain-gut axis disorders
… (IBD). Despite a growing understanding of the neurobiology of brain-gut axis dysfunction, there is a relative paucity of investigations into how the various factors involved in dysregulating the brain-gut axis, including stress, immune activation and pain, could impact on fundamental brain …

Exploring Pain Neurobiology: Molecular Investigation of Genetic Sensory Disorders
The nociceptive system is a neural pathway that underlies our capacity to feel pain when we are threatened by potential tissue injury. Congenital Insensitivity to Pain (CIP) arises when genetic mutations disrupt molecular components that are essential to the development or postnatal function of …

The Neurobiology of Social Cognition: Role of the Posterior Cingulate Cortex
<p>It has been suggested that primate brains are inherently biased towards gathering and processing the social information present in the world. In fact, the neural network that mediates our engagement with the external world - the default mode network (DMN) ¬- is strongly convergent with the …

The neurobiology of parental behaviour of the ring dove (streptopelia risoria)
The ring dove (Streptopelia risoria) expresses a stereotyped breeding cycle and has been used extensively as a laboratory animal model for studies of avian parental behaviour. Studies were undertaken to identify brain regions of the ring dove involved in the exprcssion of these behaviours, and to …

The structural neurobiology of social anxiety disorder : a clinical neuroimaging study
While a number of studies have explored the functional neuroanatomy of social anxiety disorder (SAD), comparatively few studies have investigated the structural underpinnings in SAD. 18 psychopharmacologically and psychotherapeutically naïve adult patients with a primary Axis I diagnosis of …

On the neurobiology of apathy and depression in cerebral small vessel disease
Cerebral small vessel disease (SVD) is a cerebrovascular pathology that affects the small vessels of the brain, resulting in heterogeneous brain tissue changes. These can lead to neuropsychiatric symptoms such as apathy, a loss of motivation, and depression, which is characterised by low mood and a …

Neurobiology, empathy and social cognition: the potential benefits of theatre in traumatised communities
The ubiquity of technology enables unprecedented contact between people, yet it neglects essential face-to-face communion; e-mail, text-messaging and even social media strip away the metadata of our interpersonal communications; the emotional cues and clues that are a necessary part of everyday …

Clinicians' Experiences of the Application of Interpersonal Neurobiology as a Framework for Psychotherapy
Interpersonal Neurobiology (IPNB) combines multiple fields of thought into one integrated framework. It has been utilized to expand conversation of the "mind" and promote well-being across disciplines. Current literature outlines the IPNB framework, including suggestions for its application to …

Spatial representation from birth to old age: Insights from comparative neurobiology and behavioral genomics.
Finding one’s way back to a safe refuge or recalling the best place to find food is essential to all animals including human beings. We engage in future actions based on past events. So how does our brain compute such important cognitive tasks? Is it an innate ability we have from birth that is …

Development of diffusive optical imaging as a tool for studying the neurobiology of birdsong
The goal of this project is to adapt diffusive optical imaging (DOI) to study the brains of songbirds. We study songbirds because they have a special ability to learn songs and to use them to communicate. We choose to use DOI because it has a unique potential for harmlessly measuring the brain …

Affective Social Neurobiology and Student Formation in Christian Higher Education Institutions: A Transdisciplinary Multimethod Study
… development from the field of affective social neurobiology. The meta-analysis was based on four previously conducted qualitative studies of student spiritual formation at Christian higher education institutions. Each study was individually analyzed utilizing standard grounded theory processes …

Differences in the Communicative Behavior and Neurobiology of Chimpanzees (Pan troglodytes) and Bonobos (Pan paniscus)
<p>Chimpanzees and bonobos have distinctly different vocalizations, but it is unclear why these differences have evolved. We hypothesized that differences in habitat and feeding ecology have selected for bonobos to have an increased reliance on vocal communication compared to chimpanzees. To …

The Neurobiology of Motor Skill Learning: Structural Adaptation Within Sensorimotor Regions of the Rat Brain
A second series of studies revealed the AC animals to have significantly more synapses/neuron within layer II/III of the motor cortex than control animals and that this difference was dependent on the amount of training the animals received. Changes in synapse morphology were also observed in the …
