Over the past decade, robotic neurorehabilitation has become one of the most discussed innovations in neurological recovery. Robotic gait trainers, upper-limb rehabilitation systems, exoskeletons, and AI-assisted rehabilitation devices are increasingly being adopted by hospitals and rehabilitation centres worldwide. However, an important question remains: Are robots the future of neurorehabilitation—or are they simply another tool in the rehabilitation toolbox? As clinicians and researchers, we must move beyond marketing claims and focus on scientific evidence, patient selection, and clinical reasoning. What is Robotic Neurorehabilitation? Robotic neurorehabilitation involves the use of electromechanical devices that assist, guide, resist, or augment movement during therapy. These technologies include: • Robotic gait trainers • Wearable exoskeletons • Upper limb robotic rehabilitation devices • End-effector robotic systems • Sensor-based rehabilitation platforms • AI-assiste...
The prefrontal cortex (PFC) is a critical brain
region associated with higher-order cognitive functions, including executive
function, decision-making, social behavior, and emotional regulation. The PFC
undergoes significant development across the lifespan, with distinct regions
contributing to various aspects of cognitive control and behavior. Here are the
key regions of the prefrontal cortex and their functions:
1. Orbitofrontal Cortex (BA 11):
o Location: Located in the ventromedial part of the PFC.
o Function: The orbitofrontal cortex is involved in decision-making, reward
processing, emotional regulation, and social behavior. It plays a role in
evaluating the emotional and motivational significance of stimuli and guiding
adaptive behavior based on reward outcomes.
2. Ventrolateral PFC (BA 44, 45, 47):
o Location: Situated in the lower lateral aspects of the PFC.
o Function: The ventrolateral PFC is associated with cognitive control, working
memory, language processing, and response inhibition. It plays a role in
maintaining task-relevant information, manipulating information, and regulating
attention during complex cognitive tasks.
3. Dorsolateral PFC (BA 9, 46):
o Location: Located in the upper lateral aspects of the PFC.
o Function: The dorsolateral PFC is involved in executive functions such as planning,
problem-solving, cognitive flexibility, and goal-directed behavior. It plays a
crucial role in working memory, mental manipulation of information, and
strategic decision-making.
4. Rostrolateral PFC (BA 10):
o Location: Situated in the rostral part of the lateral PFC.
o Function: The rostrolateral PFC is associated with cognitive control, attentional
processes, and multitasking. It plays a role in monitoring and coordinating
complex cognitive operations, integrating information from multiple sources,
and maintaining task sets for goal-directed behavior.
These regions of the prefrontal cortex work in
concert to support various aspects of executive function and cognitive control.
The hierarchical organization of the PFC allows for the integration of
information, the regulation of behavior, and the coordination of complex
cognitive processes. Understanding the functions of different regions within
the prefrontal cortex provides insights into the neural basis of higher
cognitive functions and the role of the PFC in adaptive behavior and
decision-making processes.
