Neuronal Connections: The Building Blocks of Thought Brain neurons, the fundamental units of the nervous system, communicate with each other through intricate connections called synapses. These synapses are the junctions where electrical signals, known as action potentials, are transmitted from one neuron to another. When a neuron fires, it releases neurotransmitters, chemical messengers that cross the synaptic gap and bind to receptors on the receiving neuron. This binding triggers a cascade of
