They are neurons that can be found in all six of cortical layers (except layer 1), and they are excitatory projection neurons.
The major cell type in cortical areas is the pyramidal neuron. These neurons have a triangular cell body and are characterized by an apical dendrite that extends towards the cortical surface. Pyramidal neurons are involved in information processing and communication within the brain.
In the external granular layer of the neocortex, you can find small pyramidal neurons and granule cells. In the external pyramidal layer, you will find predominantly small and medium pyramidal neurons.
They are present in all six layers of cortex (except layer 1). Whenever Pyramidal neurons (another type of neurons that are also found in cortical layers) are over-excited, cells of Martinotti will send inhibitory signals to surrounding neurons. Simply, they are involved in "cortical dampening mechanism".
The cortical region primarily consists of neurons, which are the main cells responsible for processing information in the brain. Additionally, glial cells such as astrocytes and oligodendrocytes provide support and insulation to neurons in the cortical region.
The "internal pyramidal layer" is the 5th layer of neocortex. You can find lots of large pyramidal neurons at this layer and they project their axons to subcortical structure.You can also find the "giant pyramidal cells of Betz" at this 5th layer of the motor areas. They are very large and they send their axons to corticospinal tract.

CRFS stands for "Cortical Response Frequency Shift", which is a phenomenon observed in neuroscience relating to changes in the frequency response of cortical neurons in the brain.
Alzheimer's disease is a condition characterized by cortical atrophy and loss of neurons, particularly in the parietal and temporal lobes of the brain. This pathology often leads to memory loss, cognitive decline, and other neurological symptoms.

Neuroscientists have studied the very large neurons in the brain, such as pyramidal neurons found in the cerebral cortex. These neurons play essential roles in functions like higher cognitive processes and motor control, making them a focus of research to understand brain functions better. By studying these neurons, researchers can gain insights into how information is processed and transmitted in the brain.
The technique of studying the brain involving the electrical activity of the large groups of cortical neurons is calles an EEG. The process of conducting an EEG is to place electrodes on different parts of the scalp and recording the electrical signals.
