We are witnessing a stark increase in scientific interest in the neurobiological processes associated with pregnancy and maternity. Convergent evidence suggests that around the time of labour, first-time mothers experience a specific pattern of neuroanatomical changes that are associated with maternal behaviour. Here we provide an overview of the human neurobiological adaptations of motherhood, focusing on the interplay between pregnancy-related steroid and peptide hormones, and neuroplasticity in the brain. We discuss which brain plasticity mechanisms might underlie the structural changes detected by MRI, which hormonal systems are likely to contribute to such neuroanatomical changes and how these brain mechanisms may be linked to maternal behaviour. This Review offers an overarching framework that can serve as a roadmap for future investigations.

The retrotrapezoid nucleus, located in the parafacial medullary region (RTN/pFRG), is crucial for respiratory activity and central chemoreception. Recent evidence suggests that neuromodulation, including peptidergic signalling, can influence the CO/H sensitivity of RTN neurons. The paraventricular nucleus of the hypothalamus (PVN) projects to the ventral medullary surface, including the RTN, and is considered the primary source of oxytocin to the brainstem.

Hypoxia can adversely affect multiple organ systems. This study investigated the impact of intermittent hypoxia on serotonin levels and depression-like behaviors across distinct neuroanatomical regions. Sixteen adult female Wistar albino rats were divided into two groups: control ( = 8) and hypoxia ( = 8).

Attention deficit hyperactivity disorder (ADHD) is a pervasive neurodevelopmental condition that typically manifests during childhood. Its symptoms manifest much earlier-often before the age of seven. With the disorder's continuous patterns of inattention, hyperactivity, and impulsiveness, it gets in the way of academic, social, and occupational performance.

Objectives: Pareidolic illusions involve perceiving meaningful objects in ambiguous or visually complex stimuli. Although seen in dementia, their presence and associated neuroanatomical basis in older adults without dementia remain unclear. Investigating these illusions in this population may reveal early neurodegenerative changes preceding overt dementia.

Introduction: Alzheimer's disease (AD) involves complex neurodegeneration in the locus coeruleus (LC) and substantia nigra (SN), critical brain regions affecting cognitive and emotional processes.
Methods: Using the National Alzheimer's Coordinating Center dataset of 11,583 participants, we conducted a multimodal analysis involving descriptive statistics, multifactorial regression, mediation analysis, and receiver operating characteristic curve assessment.
Results: LC degenerative changes (18.
