Volunteering

My First Day Volunteering at the Jack & Sheryl Morris Cancer Institute

Walking into the Jack & Sheryl Morris Cancer Institute for my first day as a volunteer, I wasn’t entirely sure what to expect. I knew I would be helping patients and staff, but I didn’t realize how much I would learn in just a single day, not only about the hospital itself, but about the incredible people who work there.

The morning began with a scavenger hunt that was meant to help the new volunteers become familiar with the building and get to know one another. I was on a team with my friend Anvita, a girl from my school named Shruti, and two other volunteers. What started as a simple orientation activity quickly became a fun way to break the ice.

We started on the fifth floor, where we walked around the hallways, introduced ourselves to staff members, asked them their names, and completed different scavenger hunt tasks. Along the way, we took pictures with different inspirational quotes displayed around the building. From there, we explored the eighth, ninth, and tenth floors. By the time we reached the top floor, we were rewarded with an incredible view of the surrounding area. It was a nice reminder that even in a place dedicated to treating serious illnesses, there were still moments of beauty.

After finishing the scavenger hunt, we returned to the first floor to meet with the rest of the volunteers and receive our assignments for the day. I was placed in the Radiation Oncology unit, located in the basement.

Originally, my role was pretty straightforward. My main job was to check in with the patients in the waiting area and ask if they needed anything, like water or blankets. However, I quickly discovered there was much more I could do to help.

Before approaching any patients, I introduced myself to the nurses and asked if there was anything needed. They immediately welcomed the extra help and asked me to assemble patient care kits for individuals receiving radiation treatment. Each kit included a patient belongings bag, an arm cuff, and the familiar yellow non-slip hospital socks. I ended up preparing twenty of these kits, and while it was a simple task, it helped keep everything organized for incoming patients and allowed the nurses to focus on providing care.

One thing that stood out to me throughout the day was how genuinely kind and appreciative the staff were. Every nurse I spoke with made me feel like I was part of the team, even though it was my very first day.

Later, I helped prepare patient rooms after treatments. I stripped the beds, disinfected the surfaces, remade the beds with fresh linens,and restocked each room with gowns, blankets, and the treatment kits I had assembled earlier. Watching each room transform from used to completely ready for the next patient gave me a new appreciation for everything that happens behind the scenes in a hospital. The work that keeps a healthcare environment running smoothly often goes unnoticed, but it plays an essential role in every patient’s experience.

As I began spending more time in the waiting area, I had the chance to interact with several patients. One small moment that stuck with me involved the infused water the unit offered. It was flavored with cucumber and strawberries, and I joked with one of the patients that it probably just looked fancy without actually tasting like either ingredient. We both laughed after trying it and realizing that it genuinely tasted like cucumber and strawberry. It was such a simple conversation, but it reminded me that even little moments of humor and connection can brighten someone’s day, especially in a hospital setting.

One of my favorite parts of the day wasn’t even one of my assigned responsibilities, but simply talking with the nurses. While I worked, one nurse shared stories about her daughter, who is my age and loves creating art. She told me about her daughter’s volunteer work at both the local library and a Chinese school, and it was inspiring to hear about another student using her time to give back to her community.

Later, the conversation shifted in a completely different direction. A nurse had been reading a book about the ethics of eating animals, which sparked a discussion among several staff members about animal welfare, food choices, and different perspectives on the issue. It wasn’t a conversation I expected to hear during a hospital shift, but I found it fascinating. It reminded me that hospitals aren't just places where medicine happens, but they’re also places where people connect, share ideas, and build relationships during the quieter moments of the day.

Around lunchtime, all of the volunteers walked over to the main Robert Wood Johnson University Hospital. Lunch vouchers were provided, so I decided to make the most of my five-dollar budget by grabbing tuna sushi and a pack of seaweed. Somehow, everything came out to less than five dollars, which felt like a small victory. More importantly, lunch gave us all a chance to relax together. We spent the break talking, laughing, and getting to know one another better. By then, the group already felt much more comfortable than we had just a few hours earlier.

After lunch, I returned to Radiation Oncology, where I continued preparing rooms, helping patients in the waiting area, and chatting with the nurses whenever there was a quiet moment. Even though my tasks seemed small on their own, I realized that each one made someone’s day a little easier, whether it was helping a patient feel more comfortable or giving a busy nurse one less thing to worry about.

At four o'clock, all of the volunteers met together again for a debrief. We reflected on our experiences, shared what we had learned, and wrapped up our first day before heading home.

Looking back, what surprised me the most was that volunteering wasn’t just about completing tasks. It was about creating a welcome environment for patients, supporting healthcare workers, and contributing to a team whose shared goal is helping others. For the first day, I couldn’t have asked for a better experience. I left the hospital with a greater appreciation for the countless people whose hard work keeps it running every day, and I’m excited to continue volunteering at the Jack & Sheryl Morris Cancer Institute. I’m looking forward to learning even more from the patients, nurses, and staff members I have the privilege of working alongside.

Plasticity Cognitive Science

Neuroplasticity: Changes in Grey Matter Induced by Training

Draganski B. et al. 2004 Nature

A landmark study demonstrating structural grey matter changes following juggling training in young adults, using voxel-based morphometry. Expansion in mid-temporal and posterior intraparietal areas was observed after three months of learning, with partial reversal following a detraining period — the first direct in vivo evidence that skill acquisition drives cortical remodelling in adults.

★★★★☆4 / 5 — Influential

Why This Matters

This paper shifts the Overton window on adult neuroplasticity. Before Draganski, the prevailing assumption was that grey matter volume was largely fixed in adulthood. Observing VBM maps change within three months of training — and partially reverse during detraining — is a remarkable result with clear implications for rehabilitation medicine and education.

Methodological Concerns

The sample size is modest (n=24), and VBM had well-documented registration sensitivity issues at the time of publication. Crucially, the paper does not disambiguate the cellular substrate of the grey matter change — whether synaptogenesis, dendritic arborisation, glial proliferation, or angiogenesis — a distinction that matters considerably for mechanistic understanding.

Personal Reflection

Despite its limitations, this is the paper I cite most often when explaining why neuroscience captivates me. The idea that a scanner can detect structural change in a healthy brain after only three months of practice feels almost implausible — which is precisely what makes it compelling.

Clinical Epilepsy

SUDEP and the Mechanisms of Sudden Death in Epilepsy

Devinsky O. 2011 Lancet Neurology

A rigorous review of sudden unexpected death in epilepsy (SUDEP), examining the epidemiology, risk factors, and proposed mechanisms, including post-ictal cardiorespiratory depression and brainstem serotonergic dysfunction. Devinsky draws on animal model data and clinical observation to argue for a multifactorial aetiology, and calls for more systematic risk communication in clinical practice.

★★★★★5 / 5 — Essential Clinical Reading

Overview

SUDEP is one of the most under-discussed risks in clinical neurology, and this review brings it into sharp focus. The epidemiology section is particularly well-organised, applying the Nashef criteria cleanly to distinguish definite, probable, and possible SUDEP.

The Serotonin Hypothesis

The mechanistic section on serotonergic pathways is the most thought-provoking part of the paper. Evidence that 5-HT1A-deficient mice show higher SUDEP rates after induced seizures — and that SSRIs may confer protection — opens a genuinely tractable therapeutic question. Translation to humans is complicated by epilepsy syndrome heterogeneity, but the signal is worth pursuing.

Clinical Implications

This paper solidified my view that SUDEP risk communication should be routine in epilepsy management, analogous to mortality risk counselling in heart failure. The evidence that nocturnal supervision may be protective is immediately clinically applicable — one need not wait for mechanistic certainty to act on it.
