    Alcohol alters brain structure at the molecular level
    Joint Spanish/English research has identified, for the first time, the structural damage caused in brain cells by excessive alcohol use. The research was published in the April 2014 biomedical sciences journal, PLOS One. This breakthrough by the...
  • Dendritic Spike
    Neuroscientists discover active role of brain dendrites
    On Oct. 27, researchers at the University of North Carolina at Chapel Hill announced that they have discovered that neuronal dendrites, which are branch-like projections of neurons, are not merely passive relays that send information between...

    Odors affect dream tone
    Neuron types are highly specific for one odor receptor type. Collectively members of the same neuron type will elicit a specific scent response from the brain. The MMB/dREAM protein complex may be the major selector, at least when smelling carbon...

    Mental games for your mind (Video)
    Your child learns by how their brain takes in and processes information. Some kids learn by listening, some may need a hands-on approach, while others learn by observing. What we see in some classrooms are lectures with worksheets – a one...

    Discovery: Brain cells age like other cells
    New research presented at the Newcastle University web site on September 11, 2012, is the first to demonstrate that brain cells age in the same processes that all other body cells do. The research was reviewed at the Eureka Alert web site the same...

    Chemical synapses: How the brain communicates chemically
    The brain uses both electrical and chemical synapses. A previous article described the electrical synapse, but this article will explain the chemical synapse.Most synaptic transmission in the human adult brain is chemical in nature, as opposed to...

    Electrical synapses of the brain: How the brain communicates electrically
    A synapse is the space between two neurons, the presynaptic and the postsynaptic neuron, and it is the channel through which neurotransmitters and electric activity are released. There are two kinds of synapses in the brain: electrical and...

    Toxins and ion channels: How toxins like the pufferfish poison damage the brain
    An action potential, or nerve impulse, is how neurons communicate electrically. One thing that an electric current does is to cause ions to move from one side of the neuronal membrane to the other. Two ions are sodium and potassium, among others....

    So you wanna know how a neuron fires: The action potential, or nerve impulse
    A nerve impulse is called an action potential, and an action potential is the reversal of the charge of the inside of a neuron.Normally, when the neuron is not firing and is considered to be at resting potential, the inside of the neuron, the...
