Tobacco smoking during pregnancy is related to many effects on health and reproduction, in addition to the general health effects of tobacco. A number of studies have shown that tobacco … Continue Reading Large-scale study finds smoking during pregnancy raises risk of schizophrenia in offspring.
Memories are formed at structures in the brain known as dendritic spines which communicate with other brain cells via synapses. It is known that the number of these brain connections … Continue Reading Study identifies cause of dendritic pruning defect linked to autism and schizophrenia.
Proneural proteins of the class I/II basic-helix-loop-helix (bHLH) family are transcription factors that are highly conserved from invertebrates to humans. Class I bHLH proteins are expressed in a broad number … Continue Reading New role revealed for neurogenesis protein associated with schizophrenia.
It is known that the hippocampus is central to episodic memory and spatial navigation both of which rely on sequences of spatiotemporal information. Spatiotemporal trajectories are coded by theta sequences, … Continue Reading Study identifies previously unknown function in the brain involving memory.
Scientists have long speculated that schizophrenia, which affects about 1 in every 100 adults worldwide, originates in part in the hippocampus, the brain’s headquarters for memory and spatial navigation. As … Continue Reading Schizophrenia linked to loss of cells in brain’s memory centre for the first time.
Differences in the size and structure of certain brain areas have been found in some adults diagnosed with schizophrenia. Early findings came from the discovery of enlarged ventricles in people … Continue Reading Neuroimaging matches specific schizophrenia behaviour to the brain’s anatomy.
In the mammalian central nervous system, neurons receive inhibitory synaptic inputs from gamma-aminobutyric acid (GABA)ergic interneurons and excitatory inputs from glutamatergic neurons. Evidence suggests that the dysfunction of appropriate GABAergic … Continue Reading Study implicates two genes in the cause of schizophrenia, vital for signalling balance.
The association between marijuana, also known as cannabis, and schizophrenia is historically fraught. In the 1960s and 1970s, scientists thought that smoking cannabis could trigger psychosis in anyone. Recent studies … Continue Reading Researchers identify link between cannabis use in young males and raised schizophrenia risk.
Individuals with schizophrenia have trouble with social interactions and in recognizing what is real. Past research has suggested that, in schizophrenia, abnormalities in the way the brain processes visual information … Continue Reading Extensive lit. review links retinal changes to brain pathology in schizophrenia.
Many genes responsible for the creation of synaptic proteins have previously shown to be strongly linked to schizophrenia and other brain disorders, however, until now the reasons have not been … Continue Reading Researchers identify schizophrenia’s ‘master-key’ gene.
Researchers from the University of Pennsylvania have found for the first time that stress during the first trimester of pregnancy alters the population of microbes living in a mother’s vagina. … Continue Reading Study finds mother’s stress alters babies’ gut and neurodevelopment through vaginal microbiome.
An international team of scientists led by Cardiff University researchers has provided the strongest evidence yet of what causes schizophrenia, a condition that affects around 1% of the global population. … Continue Reading Researchers provide strongest evidence yet of neurogenetic cause of Schizophrenia.
Previous studies have shown that the connection in the adult brain are hard to change, while in children, novel experiences rapidly mold new connections during critical periods of brain development. … Continue Reading Researchers reactivate juvenile neural plasticity in adult brains.
People with a severe form of schizophrenia have major differences in their brain networks compared to others with schizophrenia, bipolar disorder and healthy individuals, a new study from the Centre … Continue Reading Neuroimaging study begins to map alterations in human brain connections for severe schizophrenia.
Scientists from the The Scripps Research Institute (TSRI) have produced an approach that protects animal models against a type of genetic disruption that causes intellectual disability, including serious memory impairments … Continue Reading Precision medicine developed to protect against intellectual disability during neurodevelopment.
The thickness of cortical brain tissue progressively reduces as individuals develop psychosis, according to researchers of a large, multi-site study of young adults at clinical high risk. Onset of psychosis … Continue Reading Large-scale neuroimaging study links gray matter loss to psychosis development.
