What is happening when you are thinking?

Answer 1

When you are thinking, neurons in your brain are firing; they are caused to fire by inputs from the firing of other connected neurons, and the outputs of their firing causes other connected neurons to fire. However, since neurons have MANY MANY connections to many other neurons, any particular neuron is not SIMPLY or absolutely caused to fire just because one connected neuron fires, nor does its firing absolutely cause every neuron it connects to to fire; rather, neurons remember (through physical changes at synapses) which inputs have in combination been strong enough to cause them to fire, making them more sensitive and therefore likely to fire from a variety of similar inputs. Thus thinking is a neuro-chemical memory process, in which memories lead to memories by associations from within and without, and evoke ideas & concepts through novel combinations.

Answer 2

When you are thinking, your brain is actively processing and organizing information in order to generate ideas, solve problems, or make decisions. This process involves complex neural pathways and connections between different regions of the brain, such as the prefrontal cortex, hippocampus, and basal ganglia. Neurotransmitters and electrical signals facilitate communication between neurons, enabling the cognitive processes that occur during thinking.
